This weight to volume calculator converts a mass into a volume using the material’s density. Enter the mass and density above for an instant result.
Formula
Volume = Mass ÷ Density
Example
1,000 g of water (density 1 g/mL): volume = 1,000 ÷ 1 = 1,000 mL.
For other materials use their density — e.g. cooking oil is about 0.92 g/mL, so it takes more volume per gram.
Frequently Asked Questions
How do I convert weight to volume?
Divide the mass by the material’s density. For water at 1 g/mL, 1,000 g equals 1,000 mL.
Why do I need density?
Because the same weight of different materials takes different volumes; density links the two.
Is water 1 g per mL?
Very close at room temperature, which is why 1 liter of water weighs about 1 kilogram.
