About converting Foot per Sec to Speed of Light

Converting Foot per Sec to Speed of Light is a common speed conversion. One foot per sec (ft/s) equals 1.016000e-9 speed of light (c). Feet per second are used in ballistics, engineering, and some US speed calculations.

This conversion is commonly needed for running and fitness tracking, aviation and flight planning, sailing and marine navigation. The speed of light in a vacuum (about 299,792 km/s) is a universal constant used as a speed reference in physics and relativity.

To put foot per sec in perspective: a pitched baseball (about 130 ft/s). In speed of light, common references include a WiFi signal traveling across a house in a few nanoseconds.

Did you know?

Feet per second is commonly used in ballistics to describe projectile muzzle velocity, giving more intuitively sized numbers than meters per second for that range of speeds.

Real-world examples
Foot per Sec (ft/s)
  • a fast elevator (about 20 ft/s)
  • a pitched baseball (about 130 ft/s)
  • the speed of sound (about 1,125 ft/s)
Speed of Light (c)
  • light from the Sun reaching Earth in about 8 minutes
  • a laser pointer's beam crossing a room in a few nanoseconds
  • a WiFi signal traveling across a house in a few nanoseconds
Did you know?

The speed of light was the last fundamental constant measured precisely enough that in 1983 it was fixed by definition — the meter is now defined in terms of the speed of light, rather than the other way around.

Common uses for speed conversion

People frequently convert between foot per sec and speed of light for:

  • driving and speed limit compliance
  • running and fitness tracking
  • aviation and flight planning
  • sailing and marine navigation
  • physics and engineering calculations

Frequently asked questions
How do you convert Foot per Sec to Speed of Light?
To convert Foot per Sec to Speed of Light, use the formula: 1 ft/s = 1.016000e-9 c. For example, 1 ft/s = 1.016000e-9 c.
What is 1 Foot per Sec in Speed of Light?
1 ft/s is equal to 1.016000e-9 c.
How many foot per sec are in 1 speed of light?
1 c is equal to 980,000,000 ft/s. To convert Speed of Light back to Foot per Sec, multiply the speed of light value by 980,000,000.
When would I need to convert foot per sec to speed of light?
This conversion is commonly needed for physics and engineering calculations, driving and speed limit compliance, running and fitness tracking. Feet per second are used in ballistics, engineering, and some US speed calculations. The speed of light in a vacuum (about 299,792 km/s) is a universal constant used as a speed reference in physics and relativity.
What does 1 foot per sec look like in real life?
For reference, a typical foot per sec measurement is a fast elevator (about 20 ft/s). So 1 ft/s (1.016000e-9 c) gives you a practical sense of scale.
