Convert cooking measurements between weight and volume instantly — grams, kilograms, ounces, pounds, milliliters, cups, teaspoons, tablespoons, and liters. Unlike a generic unit converter, this tool factors in each ingredient's density, so 1 cup of flour and 1 cup of honey convert to the correct — and different — gram weight. Just pick your ingredient, enter any amount, and every other unit updates automatically.
Not all ingredients weigh the same by volume. A cup of water weighs about 236 grams, but a cup of honey weighs closer to 340 grams because honey is denser. Recipes that list ingredients only in cups or tablespoons can lead to inconsistent results — especially in baking, where precision matters. This calculator solves that by using each ingredient's specific density (grams per cubic centimeter) to convert accurately between metric weight, imperial weight, and volume measurements, so your measurements stay consistent no matter which system your recipe uses.
- Select your ingredient from the dropdown, or choose "Custom" to input your own density.
- Check the density value — it's pre-filled for common ingredients like water, milk, flour, sugar, and butter.
- Type your known measurement into any field (grams, cups, teaspoons, etc.).
- Every other unit — metric and imperial — updates automatically in real time.
The Formula
Core equation:
Volume (mL) = Weight (g) ÷ Density (g/mL)
and reversed:
Weight (g) = Volume (mL) × Density (g/mL)
How a User Uses It (step-by-step)
- Pick an ingredient (Water, Milk, Flour, Sugar, Honey, Butter, etc.) — this auto-fills a typical density, or choose "Custom" to enter your own.
- Confirm or adjust the density (shown in g/cm³, equivalent to g/mL).
- Enter a known amount in any field — grams, ounces, cups, teaspoons, whatever you have.
- All other units update instantly — weight and volume, metric and imperial, all at once.
