{"schema":"askedwell-earned-page-v1","url":"https://askedwell.com/pages/how-to-convert/teaspoons-to-grams","question":"How do I convert teaspoons to grams?","short_answer":"Conversion varies by ingredient. Water: 1 tsp = 5g. Salt (table): 1 tsp = 6g. Salt (Diamond Crystal kosher): 1 tsp = 3g. Sugar: 1 tsp = 4g. Flour: 1 tsp = 2.5g. Baking soda: 1 tsp = 4.6g. Baking powder: 1 tsp = 4g. Vanilla extract: 1 tsp = 4g. 1 US teaspoon = 5 mL volume.","long_answer":"Teaspoon-to-gram conversion is critical for small-quantity ingredients — baking soda, baking powder, salt, vanilla extract, spices. Unlike cups (where small errors compound), teaspoon measurements matter more proportionally because the amounts are small. A 50% error in baking soda (1.5 tsp instead of 1 tsp) ruins a recipe. Precision matters at the teaspoon level.\n\n**The standard teaspoon = 5 mL (US + metric)**\n\nNote: Australian teaspoon = 5 mL same as US. UK teaspoon historically varied but modern UK = 5 mL. Important: medical \"teaspoonful\" is different (varies by syringe/dropper; don't use for medications without specification).\n\n**Liquids (consistent — water-based):**\n\n- **Water:** 1 tsp = 5g\n- **Whole milk:** 1 tsp = 5g\n- **Heavy cream:** 1 tsp = 5g\n- **Olive oil:** 1 tsp = 4.5g\n- **Vegetable oil:** 1 tsp = 4.5g\n- **Honey:** 1 tsp = 7g (denser than water)\n- **Maple syrup:** 1 tsp = 6.7g\n- **Molasses:** 1 tsp = 7g\n- **Lemon juice:** 1 tsp = 5g\n- **Vinegar:** 1 tsp = 5g\n- **Soy sauce:** 1 tsp = 5.5g\n- **Vanilla extract:** 1 tsp = 4g\n- **Almond extract:** 1 tsp = 4g\n- **Peppermint extract:** 1 tsp = 4g\n\n**Sweeteners:**\n\n- **Granulated white sugar:** 1 tsp = 4g\n- **Brown sugar (firmly packed):** 1 tsp = 4.5g\n- **Powdered sugar:** 1 tsp = 2.5g\n- **Caster sugar:** 1 tsp = 4g\n\n**Flours (1 tsp, spoon + leveled):**\n\n- **All-purpose flour:** 1 tsp = 2.5g\n- **Bread flour:** 1 tsp = 2.5-3g\n- **Cake flour:** 1 tsp = 2.3g\n- **Whole wheat flour:** 1 tsp = 2.7g\n- **Almond flour:** 1 tsp = 2g\n- **Coconut flour:** 1 tsp = 2.3g\n- **Cocoa powder:** 1 tsp = 2g\n- **Cornstarch:** 1 tsp = 2.5g\n- **Rice flour:** 1 tsp = 3g\n\n**Leaveners (CRITICAL for baking precision):**\n\n- **Baking powder:** 1 tsp = 4g (some say 4.6g; close enough)\n- **Baking soda:** 1 tsp = 4.6g\n- **Active dry yeast:** 1 tsp = 3g\n- **Instant yeast:** 1 tsp = 3g\n- **Cream of tartar:** 1 tsp = 3g\n\n**Salt + spices (REAL variation between brands):**\n\n- **Table salt (fine):** 1 tsp = 6g\n- **Kosher salt (Diamond Crystal):** 1 tsp = 3g (lightest)\n- **Kosher salt (Morton):** 1 tsp = 5g\n- **Sea salt (fine):** 1 tsp = 6g\n- **Sea salt (coarse):** 1 tsp = 4-5g (depends on grind)\n- **Pink Himalayan salt (fine):** 1 tsp = 6g\n- **Black pepper (ground):** 1 tsp = 2g\n- **White pepper:** 1 tsp = 2g\n- **Cinnamon (ground):** 1 tsp = 2.7g\n- **Cumin (ground):** 1 tsp = 2g\n- **Paprika:** 1 tsp = 2.2g\n- **Chili powder:** 1 tsp = 2.5g\n- **Garlic powder:** 1 tsp = 3g\n- **Onion powder:** 1 tsp = 2.3g\n- **Ginger (ground):** 1 tsp = 2g\n- **Nutmeg (ground):** 1 tsp = 2.2g\n- **Turmeric:** 1 tsp = 3g\n- **Italian seasoning:** 1 tsp = 1g\n- **Dried oregano:** 1 tsp = 1g\n- **Dried basil:** 1 tsp = 1g\n- **Dried thyme:** 1 tsp = 1.2g\n- **Dried parsley:** 1 tsp = 0.5g\n\n**Other small-quantity ingredients:**\n\n- **Vanilla extract:** 1 tsp = 4g\n- **Lemon zest:** 1 tsp = 2g\n- **Espresso powder:** 1 tsp = 2g\n- **Cocoa nibs:** 1 tsp = 3g\n\n**Common teaspoon conversions to other units:**\n\n- **1 tsp = 1/3 tablespoon (tbsp)**\n- **1 tsp = 1/6 fluid ounce (US)**\n- **1 tsp = 5 mL (US + metric)**\n- **1 tsp = 1/48 cup**\n- **3 tsp = 1 tbsp**\n- **6 tsp = 1 fluid ounce**\n- **48 tsp = 1 cup**\n\n**Quick mental math (round numbers):**\n\n- **1 tsp water = 5g**\n- **1 tsp salt = 6g (table); 3g (DC kosher); 5g (Morton kosher)**\n- **1 tsp baking powder = ~4g**\n- **1 tsp baking soda = ~5g (close enough)**\n- **1 tsp vanilla = 4g**\n- **1 tsp flour = ~3g**\n\n**The salt brand difference at teaspoon scale:**\n\nThis matters even more at small quantities. A recipe asking for \"2 tsp salt\":\n- **Diamond Crystal:** 6g total\n- **Morton:** 10g total (67% more!)\n- **Table salt:** 12g total (100% more!)\n\nFor seasoning meat, dressings, baking — this is significant. Always know your salt brand.\n\n**Critical for baking (where 0.5g matters):**\n\n**Yeast (recipe says \"1 tsp yeast\"):**\n- Active dry: 3g\n- Instant: 3g\n- Pre-measured packets: usually 7g (~2.5 tsp)\n- Don't substitute interchangeably without checking\n\n**Baking soda vs baking powder:**\n- Different functions (acid vs alkaline)\n- Don't substitute 1:1\n- Recipe-specific quantities matter\n\n**The pinch + dash:**\n\nFor tiny amounts:\n- **Pinch = ~0.4g** (about 1/8 tsp salt or spice)\n- **Dash = ~0.6g** (slightly more than pinch)\n- **Smidgen = ~0.2g** (less than pinch)\n\nTools called \"pinch + dash + smidgen\" measuring sets exist for precise spice work.\n\n**For very precise baking:**\n\n- Use a digital scale that reads to 0.1g precision\n- Weigh small amounts (yeast, baking soda) for consistency\n- Reserve teaspoon measurements for tasting + non-critical seasoning\n\n**Standard measuring spoon set:**\n\nIncludes:\n- **1 tbsp (15 mL)**\n- **1/2 tbsp / 1.5 tsp**\n- **1 tsp (5 mL)**\n- **1/2 tsp**\n- **1/4 tsp**\n- **1/8 tsp**\n\nFor accuracy, level off dry ingredients with knife or finger.\n\n**Common recipe scaling:**\n\nDoubling:\n- **2 × 1 tsp = 2 tsp = 2/3 tbsp**\n\nHalving:\n- **0.5 × 1 tsp = 1/2 tsp**\n\nBy weight (more accurate):\n- **5g × 0.5 = 2.5g**\n- Math is exact, no fractional teaspoons\n\n**Why bakers prefer grams for small quantities:**\n\n1. **Yeast precision matters:** 3g ≠ 4g for proper rise\n2. **Baking soda affects pH:** small variations alter chemistry\n3. **Salt affects texture + gluten:** measure exactly\n4. **Universal language:** 3g of yeast is 3g of yeast worldwide\n5. **No \"rounded vs leveled\" ambiguity**\n\n**Common mistakes:**\n\n- **Heaping teaspoons:** dry ingredients pile up 25-50% more than leveled\n- **Eyeballing instead of measuring:** large variation between cooks\n- **Wrong salt brand without adjustment:** 50%+ over-salt or under-salt\n- **Confusing teaspoon and tablespoon:** 3× error in either direction\n- **Using kitchen serving spoons:** larger than measuring tablespoons; teaspoons are 5 mL, not \"small spoons\"\n\n**For accurate measurement:**\n\n**Dry ingredients (powders, salt):**\n1. Spoon into measuring spoon\n2. Level off with knife/finger\n3. Don't pack down (unless brown sugar with \"packed\" specified)\n\n**Liquids:**\n1. Pour into spoon over the bowl (catches overflow)\n2. Don't fill to overflowing\n3. Eye-level reading for cup measurements\n\n**Wet ingredients (paste-like):**\n1. Use solid measuring spoon\n2. Level off if measuring solid teaspoon\n3. Don't pack down extracts (just fill)\n\n**Universal tip:**\n\nFor amounts where precision really matters (yeast, baking soda, baking powder, salt):\n- **Weigh on a scale** when possible\n- **0.1g precision scale:** $25-40 (worthwhile for serious baking)\n- **Otherwise:** carefully measure teaspoon by leveling exact amount\n\n**Don't:**\n- Pack flour into teaspoon (over-weights)\n- Confuse teaspoon with tablespoon (3x error)\n- Use coffee scoop as substitute for measuring spoon\n- Trust kitchen drawer \"teaspoons\" without verifying\n- Eyeball baking powder/soda (precision matters)\n\n**Common mistakes:**\n\n- **Heaping instead of leveling:** dry ingredients overflow\n- **Different salt brands without conversion:** 30-100% variation\n- **Confusing tsp with tbsp:** triples or thirds the amount\n- **Not zeroing scale (tare) with spoon:** wrong reading\n- **Using imprecise measuring:** household \"tsp\" can be 4-7 mL\n\n**Cross-reference:** see /pages/how-to-convert/tablespoons-to-grams for tablespoon conversion + /pages/how-to-convert/cups-to-grams for cup conversion + /pages/how-to-convert/ounces-to-grams for weight conversion.\n\nMost published references (NIST Mass Standards, USDA FoodData Central, King Arthur Baking, \"The Joy of Cooking\", \"The Baking Bible\" by Rose Levy Beranbaum) converge on 5 mL volume = standard teaspoon, with ingredient-specific weight conversions especially critical for leaveners and salt in baking.","duration_iso":"PT0M","ranges":[{"condition":"1 US teaspoon (volume)","duration":"5 mL"},{"condition":"Water (1 tsp)","duration":"5g"},{"condition":"Sugar (granulated, 1 tsp)","duration":"4g"},{"condition":"All-purpose flour (1 tsp)","duration":"2.5g"},{"condition":"Salt (table, 1 tsp)","duration":"6g"},{"condition":"Salt (Diamond Crystal kosher, 1 tsp)","duration":"3g"},{"condition":"Salt (Morton kosher, 1 tsp)","duration":"5g"},{"condition":"Baking soda (1 tsp)","duration":"4.6g"},{"condition":"Baking powder (1 tsp)","duration":"4g"},{"condition":"Vanilla extract (1 tsp)","duration":"4g"}],"variables":[{"name":"Ingredient density","effect":"Water 5g; honey 7g; cocoa 2g; salt varies by brand"},{"name":"Salt brand difference","effect":"Diamond Crystal 3g; Morton 5g; table salt 6g (per 1 tsp)"},{"name":"Leveling technique","effect":"Leveled vs heaped = 25-50% difference for dry ingredients"},{"name":"Precision for leaveners","effect":"0.5g matters for baking soda/powder/yeast — use scale when possible"},{"name":"Teaspoon standard","effect":"US = 5 mL; Australian + UK + metric = 5 mL (same)"}],"sources":[{"label":"NIST Mass Standards","url":"https://www.nist.gov/pml/owm/metric-si/mass-units","note":"Official US measurement standards"},{"label":"USDA FoodData Central","url":"https://fdc.nal.usda.gov/","note":"Official US food composition database with weights"},{"label":"King Arthur Baking","url":"https://www.kingarthurbaking.com/learn/resources/ingredient-weight-chart","note":"Industry-standard ingredient weight chart with small-quantity conversions"},{"label":"Rose Levy Beranbaum, \"The Baking Bible\"","note":"Pro baker reference with precision teaspoon-to-gram conversions"}],"faq":[{"question":"Why does the teaspoon-to-gram conversion of salt depend on the brand?","answer":"Different salt brands have wildly different crystal shapes + densities. Diamond Crystal has hollow, light crystals (3g/tsp). Morton has flat denser crystals (5g/tsp). Table salt has very dense fine crystals (6g/tsp). Same volume (1 tsp) can weigh 2x as much depending on brand. For seasoning meat or precise baking, this matters. Always know your salt brand or measure by weight."},{"question":"Do baking powder and baking soda weigh the same per teaspoon?","answer":"Approximately yes — baking powder ≈ 4g/tsp and baking soda ≈ 4.6g/tsp. Close enough for most cooking. But they have different chemical roles: baking soda is alkaline + needs acid to activate; baking powder is acid + base combined (self-activating). Even though they're similar in weight, they're NOT interchangeable. Recipe-specific ratios matter more than mass conversion."},{"question":"Is \"1 tsp\" the same in Australia as in America?","answer":"Yes — teaspoons are 5 mL worldwide (US, Australia, UK, metric). This is unlike tablespoons (US = 15 mL; Australia = 20 mL). For teaspoons, recipes from any country use the same standard. If a recipe explicitly says \"scant teaspoon\" or \"rounded teaspoon\" it's usually 4 mL or 6 mL respectively — but these are non-standard variations."}],"keywords":["teaspoons to grams","tsp to g conversion","teaspoon weight conversion","how many grams in teaspoon","small quantity conversion"],"category":"baking","date_published":"2026-05-20","date_modified":"2026-05-20","license":"CC-BY-4.0","attribution":"https://askedwell.com"}
