How much acceleration is 20 km/h/s?

20 km/h/s (0.567g) is a strong acceleration — approaching 1g (9.81 m/s²), comparable to hard emergency braking or a fast elevator start.

How to Convert Kilometer Per Hour Per Second to Standard Gravity

1 kilometer per hour per second = 0.0283255 standard gravities

Standard Gravity = Kilometer Per Hour Per Second × 0.0283255

Example: 20 km/h/s × 0.0283255 = 0.56651 g

Reverse Conversion

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

  • Remember, 1 standard gravity equals 35.3039 kilometers per hour per second.
  • To convert 0.56651 g to km/h/s, multiply 0.56651 x 35.3039, resulting in 20 km/h/s.

20 km/h/s is also equal to:

  • 5.5556 meter per second squared
  • 18.227 foot per second squared
  • 555.56 gal
About these units

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

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

Frequently Asked Questions
