- m/s to km/h 1,000 m = 1 km. Divide by 1,000 to find km/s. Then, as there are 3,600 seconds in 1 hour, multiply by 3,600 to turn seconds into hours. A sound wave travels at 330 m/s. In km/h, this is: 330 ÷ 1000 = 0.33 km/s. 0.33 × 3,600 = 1,188 km/h.

The speed of sound calculator displays the speed of sound in water; it's 4672 ft/s. Let's compare it with 90 °F (warm bath temperature). The speed is equal to 4960 ft/s this time. Remember that you can always change the units of speed of sound: mph, ft/s, m/s, km/h, even to knots if you wish to.
mph to km/h: 1 mile = 1.6 km. Multiply by 1.6 to change mph into km/h. A car travels at 30 mph. In kilometres per hour this is: 30 × 1.6 = 48 km/h. km/h to m/s: 1 km = 1,000 m.
The unit of speed that is expressed in terms of kilometers and hours is written as km/h while m/s is the unit of speed which is expressed in terms of meters and seconds. Converting km/h to m/s means that we are converting the units of a given speed from kilometer per hour to meter per second.

The speed of any wave depends upon the properties of the medium through which the wave is traveling. Typically there are two essential types of properties that affect wave speed - inertial properties and elastic properties. Elastic properties are those properties related to the tendency of a material to maintain its shape and not deform whenever a ...
The speed of a sound wave in air depends upon the properties of the air, mostly the temperature, and to a lesser degree, the humidity. Humidity is the result of water vapor being present in air. Like any liquid, water has a tendency to evaporate. As it does, particles of gaseous water become mixed in the air. This additional matter will affect the ...
At normal atmospheric pressure and a temperature of 20 degrees Celsius, a sound wave will travel at approximately 343 m/s; this is approximately equal to 750 miles/hour. While this speed may seem fast by human standards (the fastest humans can sprint at approximately 11 m/s and highway speeds are approximately 30 m/s), the speed of a sound wave is ...
Like any wave, a sound wave has a speed that is mathematically related to the frequency and the wavelength of the wave. As discussed in a previous unit, the mathematical relationship between speed, frequency and wavelength is given by the following equation. Using the symbols v, λ, and f, the equation can be rewritten as The above equation is usefu...
At 20 °C (68 °F), the speed of sound in air is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s. It depends strongly on temperature as well as the medium through which a sound wave is propagating.
Convert between speed and velocity units like m/s, km/h, knots, mph and ft/s. Water - Speed of Sound vs. Temperature Speed of sound in water at temperatures ranging 32 - 212°F (0 - 100°C) - Imperial and SI units.
If the temperature is T C = 20 °C (T = 293 K), the speed of sound is v = 343 m/s. The equation for the speed of sound in air v = \(\sqrt{\frac{\gamma RT}{M}}\) can be simplified to give the equation for the speed of sound in air as a function of absolute temperature:
