Unit Converter for Cooking: Cups to Grams, Ounces to ML & More

September 5, 2026 · 4 min read

International recipes are a common source of kitchen frustration. An American recipe calls for cups, a European recipe uses grams, and a British recipe mixes both. Converting between measurement systems should not require a math degree — a quick unit converter handles it in seconds.

Essential Kitchen Conversions

1 cup of flour = 125g. 1 cup of sugar = 200g. 1 cup of butter = 227g (2 sticks). 1 tablespoon = 15 ml. 1 teaspoon = 5 ml. 1 fluid ounce = 30 ml. 1 ounce (weight) = 28g. Note that cup measurements for dry ingredients vary by ingredient — a cup of flour weighs much less than a cup of sugar.

Temperature Conversions for Baking

Most American recipes use Fahrenheit, while the rest of the world uses Celsius. Common conversions: 350°F = 175°C (standard baking), 375°F = 190°C, 400°F = 200°C, 425°F = 220°C, 450°F = 230°C. Gas mark 4 = 350°F = 175°C. For precise results, use a converter rather than rounding.

Why Weight Is Better Than Volume

Professional bakers measure by weight (grams) rather than volume (cups). A cup of flour can vary from 120g to 160g depending on how tightly you pack it. That 30% variation can ruin a recipe. A kitchen scale and gram measurements give consistent results every time.

Scaling Recipes Up or Down

When halving or doubling a recipe, unit conversion helps avoid awkward measurements. Half of 3/4 cup is 6 tablespoons (or 90ml). A third of 1 cup is about 80ml. Instead of mental arithmetic with fractions, convert to metric, scale the number, then convert back if needed.
