About converting Speed of Light to Foot per Sec

Converting Speed of Light to Foot per Sec is a common speed conversion. One speed of light (c) equals 980,000,000 foot per sec (ft/s). Celsius is used in most countries worldwide and in all scientific applications.

This conversion is commonly needed for driving and speed limit compliance, running and fitness tracking, aviation and flight planning. Feet per second are used in ballistics, engineering, and some US speed calculations.

To put speed of light in perspective: water freezes (0 °C). In foot per sec, common references include a fast elevator (about 20 ft/s).

Did you know?

The Celsius scale was invented by Swedish astronomer Anders Celsius in 1742, but he originally set 0° as boiling and 100° as freezing — it was later reversed.

Real-world examples
Speed of Light (c)
  • water freezes (0 °C)
  • a comfortable room (21 °C)
  • water boils (100 °C)
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)
