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 Mach (Sea Level)?
Mach (Sea Level) (Ma) is a unit of speed. Mach at sea level (Mach 1) is the speed of sound in air at standard sea-level conditions, approximately 340.29 meters per second (1,225 km/h). This speed varies with altitude and temperature but is standardized at sea level under ISA conditions. It serves as a dimensionless ratio comparing an object's speed to the local speed of sound [nist-sp-811]. The concept of Mach number was introduced by physicist Ernst Mach in the late 19th century to describe speeds relative to sound speed. The sea-level reference standard was adopted by aeronautical organizations to normalize measurements of supersonic speeds [nist-sp-811]. Mach number at sea level is used globally in aerospace and defense industries to specify aircraft and missile speeds. It is recognized by international standards organizations and used in flight testing and supersonic research [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, mach sea level, mach1 sea level, mach sea-level, mach speed sea level. All of these refer to the Speed of Light to Mach (Sea Level) conversion.
