Cooking Measurement Converter

Convert any recipe measurement in seconds by entering an amount and choosing the unit you have and the unit you want. Stay within volume or within weight for a direct conversion, or cross between them for a common ingredient and the tool applies its density automatically. Cups, tablespoons and teaspoons use US customary sizes, and results are trimmed to four decimals so they stay tidy on the page.

How to convert cooking measurements

  1. Type the quantity into the Amount box, for example 1.
  2. Choose your current unit in the From menu, grouped as Volume or Weight.
  3. Choose the unit you want in the To menu.
  4. When you cross volume and weight, pick the Ingredient from the list.
  5. Read the Result field and use the Copy button to grab it.

Frequently asked questions

How many grams is one cup of flour?

The tool returns 125.3916 grams for all-purpose flour. A US cup is 236.588 ml and the flour density used is 0.53 g per ml, so one cup works out to 236.588 times 0.53.

Why do I need to pick an ingredient?

Volume and weight only line up if the density is known, and density differs by ingredient. A cup of honey weighs far more than a cup of flour, so the tool asks for the ingredient only when you cross between volume and weight.

Which ingredients are supported?

Water, all-purpose flour, granulated sugar, brown sugar, butter, milk and honey each have a built-in density. Pure volume-to-volume or weight-to-weight conversions do not need an ingredient at all.

Are these US or metric cups?

Cups, tablespoons and teaspoons use US customary sizes, with 1 cup equal to 236.588 ml and 1 tablespoon equal to 3 teaspoons. Millilitres, litres, grams and kilograms are metric.

What units can I convert between?

Volume covers cups, tablespoons, teaspoons, fluid ounces, millilitres and litres. Weight covers grams, kilograms, ounces and pounds. You can mix any volume unit with any weight unit once an ingredient is chosen.

How accurate are the weight conversions?

They use standard published densities, so they are reliable for everyday cooking. Real flour varies with how it is scooped or sifted, and humidity and brand shift sugar and other staples slightly, so treat the gram figures as close estimates.

Why is the result rounded?

The output is rounded to four decimal places and trailing zeros are dropped, which keeps the number readable. That is why 1 tablespoon to teaspoons shows as 3 rather than 2.9999 or a long decimal.

Is my data private?

Yes. Every conversion runs locally in your browser with client-side JavaScript, so nothing you enter is uploaded and the tool keeps working offline once loaded.
