Conversion number between speed of sound [s] and Because gas molecules move more slowly at colder temperatures, that slows the speed of sound; sound moves faster through warmer air. miles per hour = speed of sound × 767.269148, 5 sound = (5 × 767.269148) = 3,836.345741 mph. On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is 761.2 mph (1,225 km/h). Keep reading to learn more about each unit of measure. Miles per hour can be abbreviated as mph, and are also sometimes abbreviated as mi/h or MPH.

Are You Planning a Home Improvement Project? Scientists are interested in the speed of sound, according to NASA, because it indicates the speed of transmitting a "small disturbance" (another way of describing a sound wave) through a gas medium. We're also on Facebook & Google+. Decimal places: Woman sheds coronavirus for 70 days without symptoms. One speed of sound is equal to 767.269148 miles per hour, so use this simple formula to convert: The speed in miles per hour is equal to the speed of sound multiplied by 767.269148. By 1 speed of sound = `(342.603648550333) / (0.44704)` =, 1 miles per hour = `(0.44704) / (342.603648550333)` =. This means, that speed of sound is bigger unit than miles per hour.

Speed of sound in the air. Receive news and offers from our other brands? Miles per hour can be expressed using the formula: Speed of sound and miles per hour are both units used to measure speed. The speed of sound is the distance a sound wave travels through an elastic medium. Future US, Inc. 11 West 42nd Street, 15th Floor, Since definition contain rounded number(s) too, there is no sense for high precision calculation, but if you want, you can enable it. You will receive a verification email shortly. Chuck Yeager and the X-1 research plane that broke the sound barrier in 1947. But this speed varies between 295-340 m/s depending on the air temperature and pressure. Switch to reverse conversion: This means, that speed of sound is bigger unit than miles per hour. Therefore, the speed required to break the sound barrier decreases higher in the atmosphere, where temperatures are colder. Miles per hour are a measurement of speed expressing the distance traveled in miles in one hour.[2]. Is this the funniest animal picture ever?

The transmission of the disturbance takes place as molecules in the gas hit each other. Cars speeds are measured in mpg. The speed of sound varies depending on the temperature of the air through which the sound moves. miles per hour [mph] is 766.38253523249. The velocity in miles per hour is equal to the distance in miles divided by time in hours. Definition of speed of sound unit: ≡ (1.4 x 286 x (20+273.15) )-2. Definition of miles per hour unit: ≡ 1 mi / 3600 s = 1609.344 m / 3600 s. In American public life, this is the most commonly used speed unit. From the NASA formula I calculated the speed on sea level at 20°C. Keep in mind, that converted number will be inaccurate due this rounding error! The first controlled flight to break the speed of sound — also known as Mach 1 — took place Oct. 14, 1947, when test pilot Chuck Yeager breached the barrier using Glamorous Glennis, an X-1 aircraft.
