Frequently asked questions
What is the density formula?
Density = mass ÷ volume.
What units can I use?
You can use any pair of compatible units, for example grams and milliliters.
What if the volume is zero?
Density is not calculated because division by zero is undefined.
Is it for kg / L?
Yes. If you enter mass in kg and volume in liters, the result will be in kg/L.
