Therefore, 1 mile is equivalent to 1.609344 kilometers. The units are defined as follows: An object moving at 1 "mph" per hour will cover a distance of one mile. For example, if a vehicle travels at a speed of 100 miles per hour (100 mph), it will move around 160 km per hour in the metric system. Therefore, the metric system is defined in miles (instead of kilometers) per time unit. c ( x R x T / M) c the speed of sound in an ideal gas R the molar gas constant (set at approximately 8.313,5 J) Adiabatic index (1.4 for air) T absolute temperature M the gas molar mass (dry air is. The unit of length known as a "mile" and it should not be confused with the nautical mile and very commonly used in the Anglo-American countries. If you want to know the speed of sound in a gas such as air, use this unique formula. First things first, one Mach is the speed of sound, and mph is short for miles per hour. To convert meters per second to miles per hour. Imagine, if the start shot was fired at the finish line, it would take about 0.3 seconds of time to hear the shot in the start blocks. The speed of sound in miles per hour at 20 degrees Celsius in dry air is about 767.2 miles per hour. Another example, in a 100-meter sprint, the starting shot is fired directly next to the starting blocks. speed MPH 2.998 x 10 8 m/sec x (1 km/1000 m) x (0.621 mi/1 km) x (60 sec/1 min) x (60 min/1 hr) Note all the units cancelled out, leaving only miles/hr: speed MPH (2.998 x 10 8 x 1/1000 x 0. The speed of sound is often illustrated by an example of a thunderstorm: if lightning strikes within 3 seconds of the thunder sound, then the thunderstorm is about 1 kilometer away. We can now set up the equation using these relationships so the units cancel out leaving only the desired miles/hour.
Actually, it is equivalent to 1.234,8 km/h. Definition: If an object travels at the speed of sound in air at 20 degrees Celsius for one second, it travels a distance of 343 meters per second.
