**How to calculate the mass of earth?**

Consider a body of mass m on the surface of the earth.Let the mass of the earth be M and radius of the earth be R,The distance of the body from the center of the earth will also be equal to the radius R of the earth.According to the law of gravitation,the gravitational force F of the earth acting on a body is given by:

** =6 × 10 ^{24 }kg**

## Mass of earth in kg

Thus mass of the earth is **6 × 10 ^{24 }kg. **

## How radius of earth is calculated?

Radius of the earth can be calculated from the following formula:

## Radius of earth in meters
