Convert centimeter/hour to Mach (20°C, 1 atm)
Please provide values below to convert centimeter/hour [cm/h] to Mach (20°C, 1 atm) [M], or Convert Mach (20°C, 1 atm) to centimeter/hour.
How to Convert Centimeter/hour to Mach (20°c, 1 Atm)
1 cm/h = 8.09854227405248e-09 M
Example: convert 15 cm/h to M:
15 cm/h = 15 × 8.09854227405248e-09 M = 1.21478134110787e-07 M

Centimeter/hour
Centimeter per hour (cm/h) is a unit of speed that measures the distance in centimeters traveled or covered in one hour.
History/Origin
The centimeter per hour has been used primarily in scientific and industrial contexts to measure slow rates of movement or growth, especially in fields like biology and material science. Its usage became more standardized with the adoption of the metric system in the 19th century.
Current Use
Today, cm/h is used in applications such as measuring the rate of biological growth, sedimentation, or the movement of fluids and materials in scientific research and engineering.
Mach (20°c, 1 Atm)
Mach is a unit of speed representing the ratio of an object's speed to the speed of sound in the surrounding medium, typically at 20°C and 1 atm pressure.
History/Origin
Named after physicist Ernst Mach, the Mach number was developed in the early 20th century to describe speeds relative to the speed of sound, especially in aeronautics and fluid dynamics.
Current Use
Mach is widely used in aeronautics and astronautics to express aircraft and spacecraft speeds, particularly in high-speed flight and supersonic travel contexts.
