# Universal Gravitation Calculator

getcalc.com's **Gravitational Force Calculator** is an online physics tool to calculate the magnitude of force of gravity based on Newton's law of universal gravitation, in both US customary & metric (SI) units.

## Definition & Formula

**Gravitational Force**, also known as Newton's Law of Universal Gravitation, states that the force of gravitational attraction particles is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
