`w = "m" * 1.622 m/s^2`

Enter a value for all fields

The **Weight on the Moon** calculator computes net force of gravity on a mass based on the acceleration due to gravity (**g = 1.622 m/s²**) on the Moon.

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

- (
**m**) mass

**Weight on the Moon (w):** The calculator returns weight in newtons. However, this can be automatically converted to other force units via the pull-down menu.

Weight is the force of gravity on a mass. Newton's second law formula (**F = m•a**) shows the relationship between mass, acceleration and force. The Weight on the Moon formula uses Newton's second law:

where:

- w is the weight on the moon
- m is the mass
- g
_{m}(1.622 m/s²) is the acceleration due to gravity on the moon.

The acceleration due to gravity is different based on the mass of the star, planet, moon or asteroid and the distance from its center of mass and its surface. For that reason, gravity has a lesser pull on bodies of lesser mass or density than the Earth such as the moon. The formula for acceleration due to gravity is:

g = (G•M)/R²

Where:

- g is the acceleration due to gravity.
- G is the Universal Gravitational Constant (G)
- M is the mass of the object (e.g. planet)
- R is the distance to the center of mass of the object.
