How much acceleration is 2.8 g?

2.8 g (2.8g) 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 Kilometer Per Hour Per Second

1 standard gravity = 35.3039 kilometers per hour per second

Kilometer Per Hour Per Second = Standard Gravity × 35.3039

Example: 2.8 g × 35.3039 = 98.851 km/h/s

Reverse Conversion

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

  • Remember, 1 kilometer per hour per second equals 0.0283255 standard gravities.
  • To convert 98.851 km/h/s to g, multiply 98.851 x 0.0283255, resulting in 2.8 g.

2.8 g is also equal to:

  • 27.459 meter per second squared
  • 90.087 foot per second squared
  • 2745.9 gal
About these units

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

Kilometer per hour per second: Practical acceleration unit; change in velocity of 1 km/h in 1 second.

Frequently Asked Questions
