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 Yard Per Second Squared
Yard per Second Squared: Imperial Acceleration Unit
The yard per second squared (yd/s²) is an Imperial unit of acceleration. While less common than ft/s² in engineering, it appears in some older US and British technical references. One yd/s² equals exactly 3 ft/s² or 0.9144 m/s².
Conversions to Other Units of Measurement:
- Meter per Second Squared (m/s²): 1 yd/s² = 0.9144 m/s² exactly (by definition of the international yard).
- Foot per Second Squared (ft/s²): 1 yd/s² = 3 ft/s² exactly.
- Standard Gravity (g): 1 yd/s² ≈ 0.09325 g. Standard gravity is approximately 10.728 yd/s².
- Inch per Second Squared (in/s²): 1 yd/s² = 36 in/s² exactly.
This unit provides a convenient scale for medium-range acceleration measurements in Imperial contexts, bridging the gap between ft/s² and larger units.
- Definition
- Imperial unit of acceleration; velocity change of 1 yard per second every second.
- Exact factor
- 1 yd/s² = 0.9144 m/s²
- Common equivalents
- 1 yd/s² = 3 ft/s²
- 1 yd/s² = 0.9144 m/s²
- 1 yd/s² ≈ 0.0933 g
- Context

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 Yard Per Second Squared
While the yard per second squared is uncommon in modern engineering, it provides an intuitive scale for everyday accelerations. A brisk walk acceleration is about 1 yd/s², and a car's typical acceleration is about 3-4 yd/s².
In American football physics, a wide receiver coming off the line might accelerate at 5-6 yd/s², while decelerating to make a cut involves forces of similar magnitude in the opposite direction.
Frequently Asked Questions
How many yards per second squared are in one foot per second squared?
One foot per second squared equals 13 yards per second squared. To convert, multiply the foot per second squared value by 13. For the reverse, divide the yard per second squared value by 13 (or multiply by 3).
What is 100 feet per second squared in yards per second squared?
100 feet per second squared = 33.333 yards per second squared. This is one of the most commonly searched conversions for this pair.
Is the foot per second squared-to-yard per second squared conversion exact?
Yes. The factor 13 is exact by international definition, not an approximation. Any imprecision comes only from the original measurement, not the conversion.
