# Gravity Constant

Use Gravity in Calcul.io. See what this built-in constant represents, enter it in an editable calculation, and review related values and units.

## gravity

Standard acceleration of gravity (standard acceleration of free-fall on Earth)

Try it yourself:

```calculio

## Standard Gravity

**gravity** is the standard acceleration due to gravity, conventionally used for force and load calculations near Earth.

## Local versus standard values

Weight is mass multiplied by g, but actual local gravity varies with latitude, altitude, and geology. Use [gravitationConstant](https://calcul.io/constants/gravitationConstant/index.md) for universal-gravity formulas, and [multiply()](https://calcul.io/function/multiply/index.md) to calculate a force from mass and acceleration. Keep kilograms, metres, and seconds consistent.
