The speed of sound also varies depending on the type of gas (air, pure oxygen, carbon dioxide, etc.) Receive news and offers from our other brands? Follow LiveScience on Twitter @livescience. miles per hour = speed of sound × 767.269148, 5 sound = (5 × 767.269148) = 3,836.345741 mph. You will receive a verification email shortly. 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. Enter the speed in speed of sound below to get the value converted to miles per hour. 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). Switch to reverse conversion: This means, that speed of sound is bigger unit than miles per hour. from miles per hour to speed of sound conversion. For example, 1 mile per hour can be written as 1 mph, 1 mi/h, or 1 MPH. The mile per hour is a US customary and imperial unit of speed. That stands as the fastest speed achieved to date by a jet-powered aircraft. Speed of sound in the air. Therefore, the speed required to break the sound barrier decreases higher in the atmosphere, where temperatures are colder. The speed of sound is the distance a sound wave travels through an elastic medium. Keep reading to learn more about each unit of measure. This means, that speed of sound is bigger unit than miles per hour. Decimal places: 1 speed of sound = `(342.603648550333) / (0.44704)` =, 1 miles per hour = `(0.44704) / (342.603648550333)` =. The speed of sound through air at 20 °C is equal to 343 meters per second, or roughly 767 miles per hour. Please deactivate your ad blocker in order to see our subscription offer. Miles per hour can be expressed using the formula: But this speed varies between 295-340 m/s depending on the air temperature and pressure. 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. 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). Please refresh the page and try again. Speed of sound can be abbreviated as sound; for example, 1 speed of sound can be written as 1 sound. Definition of speed of sound unit: ≡ (1.4 x 286 x (20+273.15) )-2. Thank you for signing up to Live Science. 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. (0-800). Conversion number between speed of sound [s] and Interpretation: The speed at which the body moves 1 mile (or 1609.344 metres) in 1 hour. Visit our corporate site. Receive mail from us on behalf of our trusted partners or sponsors? Because gas molecules move more slowly at colder temperatures, that slows the speed of sound; sound moves faster through warmer air. To convert a speed of sound measurement to a mile per hour measurement, multiply the speed by the conversion ratio. Live Science is part of Future US Inc, an international media group and leading digital publisher. This bacterium survived on the outside of the Space Station for an entire year, Weird 'gravitational molecules' could orbit black holes like electrons swirling around atoms, Here's the Biden-Harris plan to beat COVID-19. It can be seen today at the Smithsonian Air & Space Museum in Washington, D.C. (Image: © Air Force Test Center History Office). The velocity in miles per hour is equal to the distance in miles divided by time in hours. New York, Keep in mind, that converted number will be inaccurate due this rounding error! Woman sheds coronavirus for 70 days without symptoms. Cars speeds are measured in mpg. Miles per hour are a measurement of speed expressing the distance traveled in miles in one hour.. By 31 May 2013. There was a problem. Get hassle-free estimates from local home improvement professionals and find out how much your project will cost. Speed of sound and miles per hour are both units used to measure speed. Chuck Yeager and the X-1 research plane that broke the sound barrier in 1947. One speed of sound is equal to 767.269148 miles per hour, so use this simple formula to … The transmission of the disturbance takes place as molecules in the gas hit each other. NY 10036. 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. If conversion between speed of sound to metre-per-second and metre-per-second to miles per hour is exactly definied, high precision conversion from speed of sound to miles per hour is enabled.
