`Delta m = m_1 - m_2 `

Enter a value for all fields

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

The formula for the change between two masses is:

m = m_{1} - m_{2}

where:

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

- Nuclear Binding Energy: This is the energy created by a change in mass as in fusion.
- Percent Change in Mass or Weight
- Sum of two Masses
