# SDL_STANDARD_GRAVITY

A constant to represent standard gravity for accelerometer sensors.

Defined in <SDL3/SDL_sensor.h>

## Syntax

`#define SDL_STANDARD_GRAVITY 9.80665f`

The accelerometer returns the current acceleration in SI meters per second squared. This measurement includes the force of gravity, so a device at rest will have an value of SDL_STANDARD_GRAVITY away from the center of the earth, which is a positive Y value.

## Version

This macro is available since SDL 3.1.3.
