MPH to G Force Calculator

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.

Formula:

Gf = (V / 2.237)² / R / 9.81

Variable	Definition	Units
$Gf$	G-force	Gravitational force (g)
$V$	Speed	Miles per hour (MPH)
$R$	Radius of the curve	Meters
9.81	Gravitational acceleration	m/s²

Solved Calculations:

Example 1: Calculate G-force for a vehicle traveling at 60 MPH around a curve with a 50-meter radius.

Step	Value	Explanation
Convert speed to m/s	$60 / 2.237 = 26.82 \, \text{m/s}$	Convert MPH to m/s
Square the speed	$26.82² = 719.18$	Square the speed
Divide by radius	$719.18 / 50 = 14.38$	Divide by radius (R = 50 m)
Divide by gravity	$14.38 / 9.81 = 1.47 \, \text{g}$	Final G-force

Example 2: Calculate G-force for a cyclist at 20 MPH around a curve with a 30-meter radius.

Step	Value	Explanation
Convert speed to m/s	$20 / 2.237 = 8.94 \, \text{m/s}$	Convert MPH to m/s
Square the speed	$8.94² = 79.96$	Square the speed
Divide by radius	$79.96 / 30 = 2.67$	Divide by radius (R = 30 m)
Divide by gravity	$2.67 / 9.81 = 0.27 \, \text{g}$	Final G-force
