Definition of Kilometer Per Hour Per Second
Kilometer per Hour per Second: Automotive Acceleration
The kilometer per hour per second (km/h/s) is a practical unit of acceleration widely used in the automotive industry. It measures how quickly a vehicle's speed in km/h changes each second. This unit is intuitive for understanding vehicle performance, especially 0 to 100 km/h acceleration times.
Conversions to Other Units of Measurement:
- Meter per Second Squared (m/s²): 1 km/h/s equals approximately 0.27778 m/s² (exactly 1/3.6). This conversion is essential for physics calculations involving vehicle dynamics.
- Standard Gravity (g): 1 km/h/s is approximately 0.02832 g. A sports car that accelerates from 0 to 100 km/h in 3 seconds experiences about 0.94 g average acceleration.
- Mile per Hour per Second (mph/s): 1 km/h/s is approximately 0.62137 mph/s. This allows conversion between European and US automotive specifications.
- Foot per Second Squared (ft/s²): 1 km/h/s equals approximately 0.9113 ft/s². Used in US engineering calculations.
- Galileo (Gal): 1 km/h/s equals approximately 27.78 Gal.
This unit is particularly popular in European automotive journalism and specifications, making acceleration performance easy to understand for drivers and enthusiasts.
- Definition
- Practical acceleration unit; change in velocity of 1 km/h in 1 second.
- Exact factor
- 1 km/h/s = 1/3.6 m/s² = 0.277̄ m/s²
- Common equivalents
- 1 km/h/s = 1000/3600 m/s²
- 1 km/h/s ≈ 0.02832 g
- 1 km/h/s ≈ 0.6214 mph/s
- Context
- A car going 0-100 km/h in 5 seconds has average acceleration of 20 km/h/s (≈ 0.57 g)
Definition of Standard Gravity
Standard Gravity: Earth's Reference Acceleration
Standard gravity (symbol: g or gₙ) is the nominal gravitational acceleration of an object at Earth's surface at sea level. It is defined as exactly 9.80665 m/s². This value was established by the 3rd General Conference on Weights and Measures (CGPM) in 1901 and serves as a reference for comparing accelerations.
Conversions to Other Units of Measurement:
- Meter per Second Squared (m/s²): 1 g equals exactly 9.80665 m/s². This is the internationally agreed standard value used in science and engineering.
- Foot per Second Squared (ft/s²): 1 g is approximately 32.174 ft/s². This value is commonly used in US aerospace and engineering applications.
- Galileo (Gal): 1 g equals 980.665 Gal. Since 1 Gal = 1 cm/s², this conversion is straightforward and used in geophysical measurements.
- Kilometer per Hour per Second (km/h/s): 1 g equals approximately 35.30 km/h/s. A sports car accelerating at 1 g would gain about 35 km/h every second.
- Mile per Hour per Second (mph/s): 1 g is approximately 21.94 mph/s. Fighter pilots can experience accelerations of 9 g or more during combat maneuvers.
Standard gravity is essential in defining units like the kilogram-force and in expressing accelerations experienced by humans in vehicles, aircraft, and spacecraft.

About the Kilometer Per Hour Per Second
Car enthusiasts worldwide use this unit to compare vehicle performance. A Tesla Model S Plaid can accelerate from 0 to 100 km/h in about 2 seconds, meaning it achieves approximately 50 km/h/s—nearly 1.4 g!
For perspective: walking pace (5 km/h) accelerated from rest in 1 second equals 5 km/h/s, which feels gentle. But 100 km/h/s would pin you to your seat with nearly 3 g of force.
About the Standard Gravity
Standard gravity affects everything on Earth. When you jump, you accelerate downward at 1 g. Roller coasters can subject riders to 3-4 g during loops and drops. Fighter pilots train to withstand up to 9 g using special suits and techniques.
Interestingly, Earth's actual gravitational acceleration varies slightly by location—from about 9.78 m/s² at the equator to 9.83 m/s² at the poles—due to Earth's rotation and shape. The standard gravity value (9.80665 m/s²) is an internationally agreed reference.
