Convert speed in MPH to meters per second, square it, divide by the radius, and then divide by gravitational acceleration (9.81 m/s²).
The MPH to G Force Calculator converts speed in miles per hour (MPH) to G-force experienced during circular motion. It calculates the force exerted on a body as a multiple of Earth’s gravitational acceleration. This is particularly useful in physics, vehicle dynamics, and amusement ride design, where understanding the relationship between speed, radius, and G-force is critical for safety and performance.
