Foot per Hour
ft/h
Definition
The foot per hour is a unit of speed representing the distance of one foot traveled in one hour. It is used for measuring very slow speeds in imperial system countries, particularly for geological processes, slow machinery, or other applications requiring imperial units.
History/Origin
Foot per hour was developed in the imperial system for measuring very slow speeds, particularly in geological and industrial applications. It became useful in countries using imperial units for expressing slow velocities.
Current Use
Foot per hour is used in geological studies, slow machinery applications, and various industrial processes in countries using imperial units. It is also used in some scientific applications where imperial units are preferred.

Mach (20°C, 1 atm)
Ma
Definition
Mach at 20°C and 1 atmosphere is the speed of sound in air under these specific conditions, approximately 343.6 meters per second. It is used as a reference for measuring high speeds, particularly in aviation and aerospace applications.
History/Origin
The Mach number was named after Austrian physicist Ernst Mach and became the standard for measuring high speeds in aviation. It represents the ratio of an object's speed to the speed of sound in the surrounding medium.
Current Use
Mach is used in aviation for measuring aircraft speeds, in aerospace engineering for high-speed vehicle design, and in various applications involving high-speed motion. It is particularly important for supersonic and hypersonic flight.
