Feet per Second to Speed of Light Converter
CommonMeters per second, km/h, mph and more.
How to convert Feet per Second to Speed of Light
Multiply the feet per second value by 1.0167e-9: 1 ft/s = 1.0167e-9 c. Going the other way, 1 c = 9.8357e+8 ft/s, so divide by 1.0167e-9 or use the Speed of Light to Feet per Second converter.
About these units
Feet per Second (ft/s)
Feet per second is used for projectile speeds and some engineering calculations. 1 ft/s is exactly 0.3048 m/s, and 60 mph is 88 ft/s.
Speed of Light (c)
The speed of light in a vacuum is exactly 299,792,458 meters per second. Nothing carrying information can travel faster, and it is used to define the meter.
