teaspoons to grams — tsp → g Converter (Updated 2025)

Quick Answer: Multiply teaspoons by the ingredient’s grams per teaspoon.

  • Flour (AP): ~2.5 g per tsp (7.5 g/Tbsp ÷ 3)
  • Sugar (granulated): ~4.2 g per tsp (12.5 g/Tbsp ÷ 3)
  • Butter: ~4.7 g per tsp (14 g/Tbsp ÷ 3)
  • Water/Milk: ~5 g per tsp (1 tsp = 5 mL)
  • Olive/Vegetable Oil: ~4.5–4.7 g per tsp
  • Honey/Maple: ~7 g per tsp (21 g/Tbsp ÷ 3)
  • Table Salt: ~6 g per tsp (brand varies)

Real-world example: Quick brownies

Your recipe needs 2 tsp vanilla sugar and you’re weighing ingredients. Using the values above: 2 × 4.2 g = ~8.4 g. For 3 tsp butter, that’s 3 × 4.7 g = ~14 g (1 Tbsp).

Summary: 2 tsp sugar ≈ 8.4 g; 3 tsp butter ≈ 14 g.

Common mistakes (and easy fixes)

Assuming all teaspoons weigh the same

Flour, sugar, butter, and honey have different densities. One teaspoon won’t weigh the same across ingredients.

Takeaway: Always use ingredient-specific tsp→g values.

Packed vs. leveled spoons

Packed teaspoons over-shoot. Level with a straight edge unless “heaping” is specified.

Takeaway: Use level teaspoons for consistency.

Mixing U.S. and metric spoons

U.S. teaspoon = 5 mL; some sets vary slightly. Stick to one set for a recipe.

Takeaway: Keep measuring tools consistent from start to finish.

10-second method: teaspoons to grams

  1. Identify the ingredient (flour, sugar, butter, etc.).
  2. Use the per-tsp weight (e.g., flour 2.5 g, sugar 4.2 g, butter 4.7 g).
  3. Multiply: grams = teaspoons × g-per-tsp.
  4. Round at the end if the recipe allows.

Summary: Pick the right per-teaspoon number and multiply—done.
