Definition of Foot Per Second Squared
Foot per Second Squared: Imperial Acceleration Unit
The foot per second squared (ft/s²) is a unit of acceleration in the imperial and US customary systems. It represents the rate of change in velocity measured in feet per second for each second elapsed. This unit is commonly used in US engineering, aerospace, and automotive industries.
Conversions to Other Units of Measurement:
- Meter per Second Squared (m/s²): 1 ft/s² equals exactly 0.3048 m/s². This conversion follows from the international yard and pound agreement of 1959, where 1 foot = 0.3048 meters exactly.
- Standard Gravity (g): 1 ft/s² is approximately 0.03108 g. Earth's gravitational acceleration equals about 32.174 ft/s².
- Galileo (Gal): 1 ft/s² equals 30.48 Gal. This is useful when converting between imperial acceleration and CGS geodetic measurements.
- Inch per Second Squared (in/s²): 1 ft/s² equals exactly 12 in/s². This conversion is used in precision engineering applications.
- Mile per Hour per Second (mph/s): 1 ft/s² is approximately 0.6818 mph/s. This is relevant for vehicle acceleration specifications in the US.
The foot per second squared remains widely used in the United States for describing vehicle acceleration, ballistics, and aerospace applications.

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 Foot Per Second Squared
In the early days of rocketry and aviation in the United States, engineers used ft/s² as their primary acceleration unit. The acceleration due to gravity (32.174 ft/s²) became a fundamental constant in these calculations.
Ballistics and firearms engineering still commonly use ft/s² for bullet deceleration calculations, alongside muzzle velocities expressed in feet per second.
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.
