Mars gravity is 3.72 m/s² — about 38% of Earth's. A 70 kg person would weigh only 26.6 kg on Mars.

How to Convert Foot Per Second Squared to Standard Gravity

1 foot per second squared = 0.031081 standard gravities

Standard Gravity = Foot Per Second Squared × 0.031081

Example: 13.17 ft/s² × 0.031081 = 0.40934 g

Reverse Conversion

To convert standard gravities back to feet per second squared:

  • Remember, 1 standard gravity equals 32.174 feet per second squared.
  • To convert 0.40934 g to ft/s², multiply 0.40934 x 32.174, resulting in 13.17 ft/s².

13.17 ft/s² is also equal to:

  • 4.0142 meter per second squared
  • 401.42 gal
