Quick Reference Values
1 c = 2,997,924.58 hm/s. 5 c = 14,989,622.9 hm/s. 10 c = 29,979,245.8 hm/s. 25 c = 74,948,114.5 hm/s. 50 c = 149,896,229 hm/s. 100 c = 299,792,458 hm/s.
What is Speed of Light?
Speed of Light (c) is a unit of speed. The speed of light in vacuum is exactly 299,792,458 meters per second by definition, serving as a fundamental constant in physics and the SI system [bipm-si-brochure]. It links space and time units and defines the meter. This constant underpins electromagnetic theory and relativity. The speed of light was fixed by the 1983 CGPM resolution to define the meter precisely in terms of the distance light travels in vacuum in 1/299,792,458 seconds [cgpm-resolutions]. This replaced earlier measurement-based definitions. The speed of light is a universal constant used globally in physics, engineering, telecommunications, and astronomy. It forms the basis for defining the meter and plays a key role in GPS and high-speed data transmission standards [bipm-si-brochure].
What is Hectometers per Second?
Hectometers per Second (hm/s) is a unit of speed. Hectometers per second is a unit of speed equal to 100 meters per second, derived by dividing length in hectometers by time in seconds. It uses the SI prefix 'hecto-' combined with the base unit meter per second [bipm-si-brochure]. This unit arose from the SI system's use of prefixes to express multiples of base units for speed. It follows metric conventions established by BIPM to represent velocity in larger-scale measurements [bipm-si-brochure]. Hectometers per second are uncommon in everyday or scientific practice, where meters per second and kilometers per hour dominate. It may appear in specialized fields requiring intermediate speed units [nist-sp-811].
Common Misspellings
People often search for this conversion using these alternate spellings: speed of lite, speed of lightt, speed-of-light, speedoflight, spead of light, hecto meters per second, hectometer per second, hectameter per second, hectometres per second, hm per sec. All of these refer to the Speed of Light to Hectometers per Second conversion.
