Convert a Recipe to Metric

Cups to grams, ounces to grams, °F to °C — and back to US measurements. Free, no sign-up.

To convert a recipe to metric, swap volumes for weights using ingredient-specific gram values — 1 cup all-purpose flour = 125 g, 1 cup granulated sugar = 200 g — convert liquids to millilitres (1 US cup ≈ 237 ml), and convert oven temperatures with °C = (°F − 32) × 5⁄9. The converters and charts below do all of it for you, in both directions.

Cups to grams (ingredient-aware), °F to °C, tablespoons to ml, ounces to grams. Every converter works both ways.

Cups to Grams Conversion Chart

There is no single “cups to grams” number — a cup is a volume, and every ingredient packs that volume differently. A cup of honey weighs almost four times as much as a cup of rolled oats. Use the weight for your specific ingredient:

For weights: 1 ounce ≈ 28.35 g and 1 pound ≈ 454 g. For liquids: 1 US cup ≈ 237 ml, 1 tablespoon ≈ 15 ml, 1 teaspoon = 5 ml.

A Worked Example: Cookie Recipe, US to Metric

Here is a classic chocolate chip cookie ingredient list converted line by line. Multiply each cup amount by that ingredient's grams-per-cup, leave the spoon measures alone, and convert the oven temperature last:

Rounding to the nearest 5 g (281 g → 280 g) is fine — that's well within the accuracy of measuring by cup in the first place.

Oven Temperatures: °F to °C (and Fan Ovens)

The exact formula is °C = (°F − 32) × 5⁄9 — so 350°F ≈ 177°C. In practice you round to the nearest common dial setting, and for a fan (convection) oven you reduce the temperature by about 20°C because circulating air cooks faster:

Convert a Recipe to US Measurements

Going the other way — a European recipe in grams and Celsius that you want in cups and Fahrenheit — is the same chart in reverse. Divide grams by the ingredient's grams-per-cup: 250 g flour ÷ 125 = 2 cups; 100 g granulated sugar ÷ 200 = ½ cup. For liquids, divide millilitres by 237 for cups or by 15 for tablespoons, and convert temperatures with °F = °C × 9⁄5 + 32. Every converter on this page accepts input on either side.

Conversion Traps to Watch For

• Don't use one factor for everything.A cup of flour is 125 g but a cup of honey is 340 g. Generic “1 cup = 240 g” charts will wreck a bake — always convert per ingredient.
• Keep spoons for small amounts.Baking soda, baking powder, salt, and spices usually weigh under 5 g per teaspoon — below the reliable range of most home scales. Metric recipes use teaspoons and tablespoons for these too.
• “Imperial” isn't one system.A US pint is 473 ml but a UK pint is 568 ml; an Australian tablespoon is 20 ml versus 15 ml in the US and UK; and the metric cup used in Australia and New Zealand is 250 ml, not the US 237 ml. Check where the recipe was written.

Why Grams Beat Cups for Baking

A cup of flour can weigh anywhere from roughly 110 g to 150 g depending on whether you spoon it in gently or scoop and pack it — a swing of 20% or more that shows up directly in your crumb. Brown sugar has the same problem in reverse: “packed” means different things to different hands. A scale reads 220 g the same way every time, for everyone.

Weighing is also faster and cleaner: set the bowl on the scale, tare, pour, tare, pour. No cups to wash, no leveling with a knife. That's why professional bakers work in grams — and why converting a favorite recipe to metric once is worth the five minutes.

Scale the Recipe While You're At It

Converting units and resizing servings go hand in hand — metric makes scaling easier, since multiplying 281 g by 1.5 beats multiplying 2¼ cups. These free tools handle the serving math:
