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 Mile Per Hour Per Second
Mile per Hour per Second: US Automotive Acceleration
The mile per hour per second (mph/s) is a unit of acceleration commonly used in the United States automotive industry. It measures how quickly a vehicle's speed in miles per hour changes each second. This unit is especially relevant for the iconic 0 to 60 mph acceleration benchmark.
Conversions to Other Units of Measurement:
- Meter per Second Squared (m/s²): 1 mph/s equals exactly 0.44704 m/s². This conversion allows comparison with international SI measurements.
- Standard Gravity (g): 1 mph/s is approximately 0.04559 g. A car that goes 0-60 mph in 3 seconds experiences about 0.91 g average acceleration.
- Kilometer per Hour per Second (km/h/s): 1 mph/s equals approximately 1.60934 km/h/s. This conversion bridges US and European automotive specifications.
- Foot per Second Squared (ft/s²): 1 mph/s equals approximately 1.4667 ft/s². Useful for US engineering calculations.
- Galileo (Gal): 1 mph/s equals 44.704 Gal.
This unit dominates US automotive journalism and performance specifications, making it easy for American drivers to understand acceleration performance.
- Definition
- Practical acceleration unit; change in velocity of 1 mph in 1 second.
- Exact factor
- 1 mph/s = 0.44704 m/s² (exact)
- Common equivalents
- 1 mph/s = 1609.344/3600 m/s²
- 1 mph/s ≈ 0.04559 g
- 1 mph/s ≈ 1.6093 km/h/s
- Context
- A car going 0-60 mph in 4 seconds has average acceleration of 15 mph/s (≈ 0.68 g)
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 Mile Per Hour Per Second
The 0-60 mph time is an American automotive tradition dating back to the 1950s hot rod culture. Today's fastest production cars achieve 0-60 mph in under 2 seconds, meaning accelerations exceeding 30 mph/s (about 1.4 g).
Drag racing cars experience extreme accelerations—Top Fuel dragsters can exceed 150 mph/s (over 6.8 g) off the line, subjecting drivers to forces greater than astronauts experience during launch.
