# Momentum Calculator

## Calculator Use

Choose a calculation for momentum p, mass m or velocity 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.

### Momentum Equation for these Calculations:

Where:

p = momentum

m = mass

v = velocity

The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v). The calculator can use any two of the values to calculate the third. 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.

## Momentum calculations:

Solving for momentum, mass or velocity we can use the following formulas:

Calculate p Given m and v

Calculate momentum given mass and velocity.

Calculate m Given p and v

Calculate mass given momentum and velocity.

Calculate v Given p and m

Calculate velocity given momentum and mass.
