How much acceleration is 40 ft/s²?

40 ft/s² (1.243g) is above 1g — comparable to a rocket at liftoff (~1.2g) or a supercar launching 0-100 km/h in under 2.5 seconds.

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: 40 ft/s² × 0.031081 = 1.2432 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 1.2432 g to ft/s², multiply 1.2432 x 32.174, resulting in 40 ft/s².

40 ft/s² is also equal to:

  • 12.192 meter per second squared
  • 1219.2 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.
