Unit Explanations
Knotkn
Source UnitA knot is a unit of speed defined as one nautical mile per hour, which is equivalent to approximately 1.15078 miles per hour or 1.852 kilometers per hour. It is widely used in maritime and aviation contexts to denote the speed of vessels and aircraft. The knot provides a consistent measurement of velocity relative to the Earth's surface, taking into account the Earth's curvature in marine and aerial navigation. This unit is crucial for ensuring accurate travel and navigation calculations over long distances across the sea and air.
Current Use
The knot remains a critical unit of measurement in maritime and aviation industries, where it is used to express the speed of ships and aircraft. It is particularly significant because it aligns with nautical miles, which are used to measure distances over the Earth’s curved surface. This harmonization simplifies navigational calculations and communications.
Fun Fact
Knot as a unit of speed is used in both sea and air navigation.
Mile per Secondmi/s
Target UnitThe mile per second (mi/s) is a non-SI unit of speed that measures the distance in miles that an object travels in one second. It is primarily used in contexts where speeds are extraordinarily high, such as in aerospace or astrophysics. One mile is equivalent to 1,609.34 meters; therefore, a speed of one mile per second corresponds to 1,609.34 meters per second. This unit is rarely used in everyday contexts due to the extremely high speeds it represents, but it serves important functions in certain scientific fields.
Current Use
The mile per second is primarily used in theoretical physics, aerospace engineering, and astrophysics when discussing the speeds of objects such as spacecraft and celestial phenomena. While not commonly encountered in daily life, it provides a clear understanding of extraordinary speeds in scientific literature. Various government and research organizations may reference mile per second in reports relating to space travel and high-velocity phenomena.
Fun Fact
A mile per second is faster than the speed of sound, which is approximately 0.2 miles per second.

This unit is crucial for ensuring accurate travel and navigation calculations over long distances across the sea and air.
History & Origin
The term 'knot' originates from the method used by sailors to measure a ship's speed. In the 17th century, sailors would use a log-line, a rope with knots tied at regular intervals, thrown overboard. By counting the number of knots that passed overboard in a set time, they could calculate the ship’s speed. This practical approach was essential for navigation during long sea voyages.
Etymology: The word 'knot' comes from the old practice of tying knots in a measuring line or rope used to measure speed at sea.

Mile per Second
speed • Non-SI
Definition
The mile per second (mi/s) is a non-SI unit of speed that measures the distance in miles that an object travels in one second. It is primarily used in contexts where speeds are extraordinarily high, such as in aerospace or astrophysics. One mile is equivalent to 1,609.34 meters; therefore, a speed of one mile per second corresponds to 1,609.34 meters per second. This unit is rarely used in everyday contexts due to the extremely high speeds it represents, but it serves important functions in certain scientific fields.
History & Origin
The concept of measuring speed has existed for centuries, with the mile being derived from the Roman 'mille passus', meaning 'a thousand paces'. The use of miles as a measurement of distance became standardized in England during the 14th century. The second, derived from the division of an hour into 60 minutes and each minute into 60 seconds, has been in use since at least the 14th century as well. As technology progressed, particularly in the fields of astronomy and aviation, the need for measuring speed in terms of miles per second emerged.
Etymology: The term 'mile' originates from the Latin 'mille', meaning 'thousand', and 'second' is derived from the Latin 'secundus', meaning 'following' or 'next'.
Current Use
The mile per second is primarily used in theoretical physics, aerospace engineering, and astrophysics when discussing the speeds of objects such as spacecraft and celestial phenomena. While not commonly encountered in daily life, it provides a clear understanding of extraordinary speeds in scientific literature. Various government and research organizations may reference mile per second in reports relating to space travel and high-velocity phenomena.
💡 Fun Facts
- •A mile per second is faster than the speed of sound, which is approximately 0.2 miles per second.
- •The speed of light is about 186,282 miles per second, demonstrating how extraordinary speeds can be.
- •In a year, at a speed of 1 mile per second, an object would cover over 31.5 million miles!
