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.
Centimeter Hourcm/h
Target UnitThe centimeter hour (cm/h) is a non-standard unit of speed defined as the distance of one centimeter traveled in one hour. This unit is particularly useful in contexts where very small distances are relevant, allowing for precise measurements in fields like microengineering and robotics. Speed in cm/h is derived from the metric system, which is based on multiples of ten. This unit is often used in scientific contexts where describing tiny movements over extended periods is necessary, providing a clear understanding of velocity on a micro scale.
Current Use
Today, the centimeter hour is primarily used in niche applications where minute speeds are essential. It finds relevance in fields such as robotics, where precise movements are crucial for function and design. Additionally, in biomechanics, researchers may measure very slow movements of biological entities in cm/h to understand their mechanics better. The centimeter hour, while not commonly used in everyday applications, serves as a critical unit in scientific research and engineering disciplines that require a high degree of accuracy.
Fun Fact
The centimeter hour is rarely used outside of specialized scientific contexts.

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.
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.

Centimeter Hour
speed • Non-SI
Definition
The centimeter hour (cm/h) is a non-standard unit of speed defined as the distance of one centimeter traveled in one hour. This unit is particularly useful in contexts where very small distances are relevant, allowing for precise measurements in fields like microengineering and robotics. Speed in cm/h is derived from the metric system, which is based on multiples of ten. This unit is often used in scientific contexts where describing tiny movements over extended periods is necessary, providing a clear understanding of velocity on a micro scale.
History & Origin
The centimeter hour emerged from the metric system, which was established during the French Revolution in the late 18th century. The metric system aimed to create a universal standard of measurement that was decimal-based, allowing for easier calculations and conversions. The centimeter, as a subdivision of the meter, was introduced for its practicality in everyday use, while the hour has long been used as a standard unit of time. As technology advanced, particularly in fields requiring precision at small scales, the centimeter hour became relevant for measuring slow speeds in various scientific applications.
Etymology: The term 'centimeter' comes from the French 'centimètre', which combines 'centi-' meaning one hundredth and 'mètre' meaning meter. 'Hour' comes from the Latin 'hora', which has its origins in ancient Greek.
Current Use
Today, the centimeter hour is primarily used in niche applications where minute speeds are essential. It finds relevance in fields such as robotics, where precise movements are crucial for function and design.
