The **Sum of Masses **calculator computes the sum of two masses (m_{1} and m_{2}).

**INSTRUCTIONS**: Choose units and enter the following:

- (
**m**) Mass 1_{1} - (
**m**) Mass 2_{2}

**Change in Mass(m): **The calculator returns the sum of the two masses (**m**) in atomic units (u). However, this can be automatically converted compatible units via the pull-down menu.

#### The Math / Science

The formula for the sum of two masses is:

m = m_{1} + m_{2}

where:

- m is the sum of the two masses
- m
_{1}is the first mass - m
_{2}is the second mass
