Cooking Measurement Converter
Convert recipes between US, Imperial, and Metric units. Handles fractions, ingredient densities, and weight ⇄ volume.
Convert any cooking measurement between US, Imperial (UK), and Metric units. This converter handles fractions like 1/2 and mixed numbers like 2 1/2, supports volume-to-weight conversions (when you pick an ingredient), and works instantly with no signup.
Examples: 1 cup (US) → 236.588 mL · 1/2 cup → 8 tbsp (US) · 200 g flour → ~1.667 cups (US)
How to use this converter
Type in the amount (fractions like 1/2 or mixed numbers like 2 1/2 are supported), pick a measurement system to filter the unit lists, choose your From and To units, and tap Convert. If you're converting between volume (cups, tablespoons, milliliters) and weight (grams, ounces), pick the ingredient, different ingredients have different densities, so a cup of flour weighs different from a cup of sugar.
Common conversions
- 1 US cup = 16 tablespoons = 48 teaspoons = 236.588 mL = 8 fluid ounces
- 1 stick of butter = 1/2 cup = 8 tablespoons = 113 grams = 4 ounces
- 1 cup all-purpose flour ≈ 120 grams (the exact weight depends on how packed it is)
- 1 cup granulated sugar ≈ 200 grams
- 1 teaspoon = 1/3 tablespoon = ~4.93 mL (US) / ~5.92 mL (Imperial)
Why ingredient density matters
When a recipe says "1 cup of flour" it's telling you a volume. But flour is sold by weight (grams). The same one-cup measure contains 120 g of all-purpose flour, 200 g of sugar, or 227 g of butter, because each ingredient packs into the cup differently. This is why bakers prefer weighing ingredients: a gram is always a gram, but a cup of flour can vary by 20% or more depending on how packed it is. The converter handles this for you when you pick an ingredient.
