p = density
M = mass
V = volume
The Density Calculator uses the formula that density (p) is equal to mass (M) divided by volume (V) or p=M/V. The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume. Along with values, enter the known units of measure for each and this calculator will convert among units.
For example, 4 significant figures for 165778 will become 165800 while 4 significant figures for 0.00165778 will become 0.001658. See also our help notes on significant figures.
p = M/V
density, p = mass/volume
Solving for density, mass or volume we can use the following formulas:
