What is the Recipe Unit Converter & Scaler?
Recipes from other countries or older cookbooks often use cups and spoons instead of grams, or the wrong servings for your table. This tool has two calculators in one: a cooking measurement converter for volume (cups, tablespoons, teaspoons, millilitres, litres, fluid ounces) and weight (grams, kilograms, ounces, pounds), and a recipe scaler that multiplies every ingredient when you change the number of servings.
Volume-to-weight conversion depends on the ingredient's density, so the converter includes presets for water, flour, sugar, butter and rice as well as a generic option, and shows the result to two decimal places so measuring cups and kitchen scales stay accurate.

Questions people ask
How many grams are in a cup of flour?
About 120 g of plain flour per US cup, though it varies with how tightly it is packed; this tool uses a standard average.
How do I double a recipe?
Use the scaler: enter the original servings, twice that number as the new servings, and each ingredient amount.
Is a US cup the same as a UK cup?
No — a US cup is 236.6 ml and an Australian/UK metric cup is 250 ml. Check which your recipe uses.
Why does butter convert differently from water?
Butter is less dense than water, so the same cup weighs less in grams — the butter preset accounts for this.
Can I convert teaspoons to millilitres?
Yes, 1 US teaspoon is 4.93 ml, included as a direct option.
