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.

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 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.
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.
