How to calculate g-force using x, y, z values ​​from an accelerometer in Android 1.6

If the accelerometer measures acceleration in meters per second squared (SI unit), you can convert each acceleration to a g-force measurement by dividing by 9.81.

If you want the g-force to be measured without indicating direction, you just need to apply the pythagorean theorem to the various acceleration components:

double g = Math.sqrt(x * x + y * y + z * z);
