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 Inch Per Second Squared
Inch per Second Squared: Precision Engineering Acceleration
The inch per second squared (in/s²) is a unit of acceleration used primarily in precision engineering and mechanical applications in the United States. It represents the change in velocity measured in inches per second for each second elapsed.
Conversions to Other Units of Measurement:
- Meter per Second Squared (m/s²): 1 in/s² equals exactly 0.0254 m/s². This follows from the international inch definition of 25.4 mm.
- Foot per Second Squared (ft/s²): 1 in/s² equals exactly 1/12 ft/s² ≈ 0.08333 ft/s². This is a simple fraction conversion within imperial units.
- Standard Gravity (g): 1 in/s² is approximately 0.00259 g. Very small compared to Earth's gravity.
- Galileo (Gal): 1 in/s² equals 2.54 Gal. Since 1 inch = 2.54 cm exactly.
- Kilometer per Hour per Second (km/h/s): 1 in/s² equals approximately 0.0914 km/h/s.
This unit is often used in vibration analysis, precision manufacturing specifications, and mechanical engineering documents in inch-based systems.

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 Inch Per Second Squared
While less common than other acceleration units, in/s² finds use in precision machinery and vibration specifications. Sensitive scientific instruments might have vibration tolerances specified in milli-inches per second squared.
In seismology, some older American instruments recorded ground acceleration in in/s², though modern seismographs typically use metric units or gravitational fractions.
Frequently Asked Questions
How many inches per second squared are in one foot per second squared?
One foot per second squared equals 12 inches per second squared. To convert, multiply the foot per second squared value by 12. For the reverse, divide the inch per second squared value by 12 (or multiply by 112).
What is 10 feet per second squared in inches per second squared?
10 feet per second squared = 120 inches per second squared. This is one of the most commonly searched conversions for this pair.
Is the foot per second squared-to-inch per second squared conversion exact?
Yes. The factor 12 is exact by international definition, not an approximation. Any imprecision comes only from the original measurement, not the conversion.
