The product of mass and the force due to gravity is known as weight. Weight is a measure of the force exerted on an object due to the gravitational pull of a planet or other celestial body. The formula for weight is:

```

Weight = Mass x Gravity

```

where:

- Weight is measured in newtons (N)

- Mass is measured in kilograms (kg)

- Gravity is measured in meters per second squared (m/s²)
