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)
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 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.
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.
