Calculator inputs
Formula used
Volume to mass: grams = millilitres × density
Mass to volume: millilitres = grams ÷ density
Density connects volume and mass. Each ingredient has a different density. Accurate results require an appropriate density value.
The temperature option adjusts density from its 20°C reference. The correction uses an expansion coefficient. It remains an estimate for practical conversions.
How to use the calculator
- Select volume-to-mass or mass-to-volume conversion.
- Choose an ingredient or enter a custom density.
- Select the input and output measurement units.
- Enter one value or several batch values.
- Set temperature and precision options when needed.
- Calculate, then copy, print, or export results.

Frequently asked questions
Is 1 mL always equal to 1 gram?
No. That relationship is approximately true for water. Other substances need their own density values.
Why do flour and sugar differ?
Their particle shapes and packing differ. Moisture also changes their measured density. Use ingredient-specific values for better estimates.
Can I convert grams back to millilitres?
Yes. Select the mass-to-volume conversion mode. The calculator divides mass by density.
Which cup and spoon standards are used?
The calculator uses US customary cooking measures. A cup equals about 236.588 millilitres. Regional measures can differ.
How accurate are preset densities?
They are practical reference values. Brands and temperatures can produce different densities. Laboratory work needs measured density data.
What is a custom density?
It is a density you provide. Enter grams per millilitre at 20°C. This supports uncommon ingredients and materials.
What does temperature adjustment do?
It estimates density changes caused by thermal expansion. The result depends on the expansion coefficient. It should not replace measured data.
Can I calculate many values together?
Yes. Enter values in the batch box. Separate them using commas, spaces, semicolons, or lines.
What are significant figures?
They control meaningful digits rather than decimal places. This is useful for scientific measurements. Choose the required precision before calculating.
Why can powdered ingredient results vary?
Scooping and compacting change bulk density. Humidity can also change powder mass. Weighing remains the most reliable cooking method.
