How much acceleration is 3 g?

3 g (3g) is above 1g — comparable to a rocket at liftoff (~1.2g) or a supercar launching 0-100 km/h in under 2.5 seconds.

Did you know? Roller coaster (peak) is 30 m/s².

Extreme roller coasters can pull 3-6g (29-59 m/s²) during tight turns and loops.

How to Convert Standard Gravity to Mile Per Hour Per Second

1 standard gravity = 21.9369 miles per hour per second

Mile Per Hour Per Second = Standard Gravity × 21.9369

Example: 3 g × 21.9369 = 65.811 mph/s

Reverse Conversion

To convert miles per hour per second back to standard gravities:

  • Remember, 1 mile per hour per second equals 0.0455854 standard gravities.
  • To convert 65.811 mph/s to g, multiply 65.811 x 0.0455854, resulting in 3 g.

3 g is also equal to:

  • 29.42 meter per second squared
  • 96.522 foot per second squared
  • 2942 gal
About these units

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

Mile per hour per second: Practical acceleration unit; change in velocity of 1 mph in 1 second.
