kilometer/hour to Mach (20°C, 1 atm)
Please provide values below to convert kilometer/hour [km/h] to Mach (20°C, 1 atm), or change ↔.
kilometer/hour [km/h]
Definition: A kilometer per hour is a unit of speed equal to the distance traveled in kilometers divided by time in hours.
Historyandorigin: It is part of the metric system.
CurrentUse: It is widely used for measuring road speed.
funfact: One kilometer per hour is approximately 0.27778 meters per second.
Mach (20°C, 1 atm)
Definition: The speed of sound in air at 20°C and 1 atmosphere of pressure is approximately 343 meters per second.
Historyandorigin: It is based on the properties of air.
CurrentUse: It is used in aerodynamics.
funfact: Mach 1 is the speed of sound.

How to Convert kilometer/hour to Mach (20°C, 1 atm)
1 kilometer/hour [km/h] = 0.0008084336 Mach (20°C, 1 atm)
1 Mach (20°C, 1 atm) = 1236.96 kilometer/hour [km/h]
we use cross multiplication method
kilometer/hour [km/h] → Mach (20°C, 1 atm)
1 → 0.0008084336
1.5 → ?( suppose x)
=>1.5*0.0008084336=1*x
by simplifying
x=0.0012126504
