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 Miles per Second?
Miles per Second (mi/s) is a unit of speed. Miles per second (mi/s) measure speed as the number of miles traveled in one second. One mile per second equals exactly 1,609.344 meters per second, based on the international mile defined by the International System of Units (SI) conventions [bipm-si-brochure]. This unit is primarily used in astrophysics and aerospace contexts where extremely high speeds are involved. The mile originated from the Roman mille passus, standardized as 5,280 feet in the United States and the United Kingdom by the 19th century. The second as a time unit was refined by international agreement through SI standards in the 20th century, enabling miles per second as a coherent speed unit [nist-si-guide]. Miles per second is rarely used in everyday contexts but appears in scientific fields like astronomy and space exploration in the US and UK. It complements SI units in aerospace engineering, especially where imperial units prevail alongside metric [bipm-si-brochure].
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, mile per second, miles per sec, miles per s, mileps. All of these refer to the Speed of Light to Miles per Second conversion.
