# Density Calculator

## Calculator Use

Choose a calculation for density p, mass m or Volume V. Enter the other two values and the calculator will solve for the third in the selected units. You can also enter scientific notation such as 3.45e22.

### Density Equation for these Calculations:

Where:

p = density

m = mass

V = volume

The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (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.

### Significant Figures

For a value of 165778, selecting 4 significant figures will return 165800. For a value of 0.00165778, selecting 4 significant figures will return 0.001658. See also our help notes on significant figures.

## Density calculations:

Solving for density, mass or volume we can use the following formulas:

Calculate p Given m and V

Calculate density given mass and volume.

Calculate m Given p and V

Calculate mass given density and volume.

Calculate V Given p and m

Calculate volume given density and mass.

Cube root of Volume, is shown to help in the mental visualization of the actual volume. Thanks again to the user who suggested this calculator!
