Calculate g-Force from Vertical and Horizontal Acceleration

Calculator for the resulting g-force from Earth's gravity and the acceleration on a horizontal plane. This is the force, which on Earth acts on an accelerating person or item. The gravity acceleration, which is pulling down, is 1 g. The perpendicular acceleration forward usually is lower.
Please enter two of the three values and choose the units, the third value will be calculated.

Gravity acceleration:
Horizontale acceleration:

Round to decimal places.

Example: when accelerating forward with 1 g, a force of 1.414 g is in effect.

The formula for the calculation is the Pythagorean theorem: g-force = √ gravity acceleration² + horizontale acceleration²
