Mach (speed of sound)
Definition
Mach is a dimensionless unit representing the ratio of an object's speed to the local speed of sound. Mach 1 equals the speed of sound (approximately 343 m/s or 1,235 km/h at sea level in standard conditions).
History
The Mach number was named after Ernst Mach, an Austrian physicist who studied supersonic motion in the 19th century. It became critical during World War II and the subsequent development of jet and rocket aircraft.
Current use
Mach numbers are essential in aerospace engineering, military aviation, and supersonic transport. Fighter jets, commercial aircraft approaching transonic speeds, and spacecraft re-entry velocities are all described using Mach.
Feet per second (ft/s)
Definition
Feet per second (ft/s or fps) is an imperial unit of speed measuring the number of feet traveled in one second. 1 ft/s ≈ 0.3048 m/s.
History
Feet per second has been used in ballistics and engineering since the development of firearms and artillery. It was a natural unit in the foot-pound-second (FPS) system widely used in British and American engineering.
Current use
Feet per second is commonly used in ballistics (bullet velocity), engineering calculations in the US, water flow measurements, and some HVAC applications. It appears frequently in American technical specifications.
