What is Feet per Second Squared?
Feet per second squared (ft/s²) is a unit of acceleration in the imperial system. It represents the rate of change of velocity in feet per second over a period of one second. In other words, if an object accelerates at 1 ft/s², its velocity increases by 1 foot per second every second.
Feet per second squared is commonly used in engineering applications in countries that use the imperial system. Our acceleration conversion tool helps you easily convert between ft/s² and other units. For example, 1 ft/s² equals approximately 0.3048 m/s² or 0.031 g.
What is the SI Unit of Acceleration?
The SI unit of acceleration is meters per second squared (m/s²). It serves as the fundamental unit for measuring acceleration in the metric system. All other acceleration units in the metric system are derived from the m/s²:
- Kilometers per second squared (km/s²) = 1,000 m/s²
- Centimeters per second squared (cm/s²) = 0.01 m/s²
- Millimeters per second squared (mm/s²) = 0.001 m/s²
What is Feet per Second Squared Used For?
Feet per second squared is used primarily in engineering contexts in the United States and other countries that use the imperial system. It's particularly relevant in:
Vehicle Engineering
Measuring vehicle acceleration and braking performance. For example, a sports car might accelerate from 0 to 60 mph in 3 seconds, which is about 30 ft/s².
Construction & Structural Analysis
Calculating forces on buildings and structures during seismic events or wind loads. Engineers use ft/s² to determine how structures respond to dynamic loads.
Mechanical Engineering
Designing machinery and equipment where acceleration forces are important. For example, conveyor systems or roller coasters where acceleration affects performance and safety.
Physics Education
Teaching concepts of motion and acceleration. In the US, students often learn about acceleration using ft/s² before transitioning to metric units.
Etymology and History
The unit "feet per second squared" is derived from the imperial system's base units of length (foot) and time (second). The foot has its roots in human body measurements, with historical definitions based on the length of a human foot. The modern foot is defined as exactly 0.3048 meters.
Acceleration as a concept became important with the development of physics, particularly Newton's laws of motion in the 17th century. The ft/s² unit emerged as a practical way to express acceleration in systems using imperial measurements. While most scientific work now uses metric units, ft/s² remains relevant in certain engineering contexts in the United States.
Frequently Asked Questions
How do I convert ft/s² to m/s²?
To convert feet per second squared to meters per second squared, multiply by 0.3048. For example, 10 ft/s² = 10 × 0.3048 = 3.048 m/s². You can use our ft/s² conversion calculator above for instant results with any value.
What is the relationship between ft/s² and gravity?
Standard gravity (g) is approximately 32.174 ft/s². This means that an object in free fall near Earth's surface accelerates at about 32.174 ft/s². To convert ft/s² to g, divide by 32.174. For example, 16.087 ft/s² is approximately 0.5 g.
Why is ft/s² used instead of m/s² in some contexts?
Feet per second squared is used primarily in the United States and other countries that still use the imperial system. In engineering and physics applications in these regions, ft/s² provides a convenient unit that aligns with other imperial measurements like feet for distance. However, the scientific community predominantly uses m/s².
How accurate is the ft/s² conversion?
Our ft/s² conversion tool uses the internationally accepted conversion factor of 1 ft = 0.3048 m, which is exact. This makes conversions between ft/s² and m/s² highly accurate. For other units, we use precise conversion factors based on established scientific standards.
What are common values for acceleration in ft/s²?
Common acceleration values include: Earth's gravity (32.174 ft/s²), typical car acceleration (0-60 mph in 6 seconds ≈ 15 ft/s²), and high-performance sports cars (0-60 mph in 3 seconds ≈ 30 ft/s²). Braking deceleration in cars might range from 15-30 ft/s².
Can I use this tool for engineering calculations?
Yes, our ft/s² conversion tool provides accurate results suitable for most engineering applications. However, for critical applications, always verify with your specific industry standards and consider significant figures in your calculations. The tool is also useful for educational purposes and quick reference.
