How to Convert Standard Gravity to Foot Per Second Squared

1 standard gravity = 32.174 feet per second squared

Foot Per Second Squared = Standard Gravity × 32.174

Example: 40 g × 32.174 = 1287 ft/s²

Reverse Conversion

To convert feet per second squared back to standard gravities:

  • Remember, 1 foot per second squared equals 0.031081 standard gravities.
  • To convert 1287 ft/s² to g, multiply 1287 x 0.031081, resulting in 40 g.

40 g is also equal to:

  • 392.27 meter per second squared
  • 39227 gal
About these units

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

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