About converting Knot to Speed of Light

Converting Knot to Speed of Light is a common speed conversion. One knot (kn) equals 1.714813e-9 speed of light (c). Knots are the standard speed unit in maritime and aviation worldwide.

This conversion is commonly needed for driving and speed limit compliance, running and fitness tracking, aviation and flight planning. Celsius is used in most countries worldwide and in all scientific applications.

To put knot in perspective: a cruise ship (about 20 kn). In speed of light, common references include water freezes (0 °C).

Did you know?

The term 'knot' originated from counting knots on a rope trailing behind a ship over a fixed time period.

Real-world examples
Knot (kn)
  • a cruise ship (about 20 kn)
  • a sailboat in good wind (about 6–8 kn)
  • a Category 1 hurricane (64–82 kn)
Speed of Light (c)
  • water freezes (0 °C)
  • a comfortable room (21 °C)
  • water boils (100 °C)
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.
