Frequently Asked Questions
What is Mach speed?
Mach is a ratio comparing an object's speed to the speed of sound in air. Mach 1 equals the speed of sound (approx. 343 m/s or 1,235 km/h) at sea level under standard atmospheric conditions.
How many mph is 100 km/h?
100 kilometers per hour is approximately 62.1371 miles per hour.
Why do airplanes use knots instead of km/h or mph?
Knots are based on nautical miles, which relate closely to lines of latitude and longitude. This makes them especially useful for navigation over the Earth's curved surface.
Are m/s and km/h interchangeable?
They measure the same quantity (speed), but 1 m/s = 3.6 km/h. So, they are not numerically equivalent and require conversion.
