About converting Speed of Light to Km per Hour

Converting Speed of Light to Km per Hour is a common speed conversion. One speed of light (c) equals 1,100,000,000 km per hour (km/h). 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. Kilometers per hour are used for road speed limits in most countries outside the US.

To put speed of light in perspective: water freezes (0 °C). In km per hour, common references include a jogger (about 10 km/h).

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)
Km per Hour (km/h)
  • a jogger (about 10 km/h)
  • a highway speed limit (100–120 km/h)
  • a high-speed train (300+ km/h)

Common uses for speed conversion
