About These Units

About Knot

The Knot is common unit of velocity or speed, which is mostly referred to at sea as a measurement of boat, wind or water current velocity. One Knot is equal to one nautical mile per hour. The word comes from a former method of measuring a ship's speed, which used a knotted cord called the log line.

About Kilometer/second

Kilometer per second is a high-velocity unit measuring 1000 meters per second. Used primarily in aerospace, astronomy, and ballistics for describing very fast-moving objects such as spacecraft, missiles, orbital velocities, and escape velocities. This unit is essential for space exploration calculations and high-energy physics applications.
