Weight = Mass × Gravity

Where:

- Weight is the force of gravity on an object, measured in newtons (N).

- Mass is the amount of matter in an object, measured in kilograms (kg).

- Gravity is the acceleration due to gravity, which is approximately 9.8 meters per second squared (m/s²).

To calculate the weight of an object, simply multiply its mass by the acceleration due to gravity. For example, if an object has a mass of 10 kilograms, its weight would be:

```

Weight = 10 kg × 9.8 m/s² = 98 N

```

The weight of an object can vary depending on the gravitational field it is in. For example, if you weigh yourself on Earth, you will weigh more than if you weigh yourself on the Moon, because the gravitational field on the Moon is weaker.

The formula for weight is a fundamental equation in physics, and is used in many different applications, such as engineering, aerospace, and medicine.
