Density Calculator
Solve density, mass, or volume with ρ = m / V.
Leave the value you want to find as 0.
Mass packed into space
Density is mass divided by volume, and it decides whether something floats, how heavy a block of material is, and how to identify a substance. The relationship rearranges three ways.
A 100 gram object filling 50 cubic centimetres has a density of 2 g/cm³ — twice that of water, so it sinks. Set any one field to zero and the calculator solves for it.
Versatile and private
It rearranges ρ = m/V in your browser, so nothing you enter is uploaded.
Frequently Asked Questions
What is density?
Mass per unit volume. It tells you how tightly packed a material is, and whether it floats or sinks.
Can it solve for mass or volume?
Yes. Set the quantity you want to find to zero and it solves for it from the other two.
What units are used?
Mass in grams and volume in cubic centimetres give density in grams per cubic centimetre — water is about 1.
