How much acceleration is 121 ft/s²?

121 ft/s² (3.761g) is several g-forces — comparable to a fighter jet in a sharp turn (4-8g) or a Formula 1 car under heavy braking.

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: 121 ft/s² × 0.031081 = 3.7608 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 3.7608 g to ft/s², multiply 3.7608 x 32.174, resulting in 121 ft/s².

121 ft/s² is also equal to:

  • 36.881 meter per second squared
  • 3688.1 gal
About these units

Foot per second squared: Imperial/US unit of acceleration; change in velocity of 1 foot per second in 1 second.

Standard gravity: Nominal gravitational acceleration at Earth's surface, defined as exactly 9.80665 m/s².
