How much acceleration is 1.4 g?

1.4 g (1.4g) 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? Sports car (0-60 mph) is 15 m/s².

A sports car doing 0-60 mph in 4 seconds averages about 6.7 m/s² (0.68g).

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: 1.4 g × 35.3039 = 49.426 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 49.426 km/h/s to g, multiply 49.426 x 0.0283255, resulting in 1.4 g.

1.4 g is also equal to:

  • 13.729 meter per second squared
  • 45.044 foot per second squared
  • 1372.9 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
