![]() Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. Speed of sound and kilometers per second are both units used to measure speed. For example, heres how to convert 5 speed of sound to kilometers per second using the formula above. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. The speed in kilometers per second is equal to the speed of sound multiplied by 0.343. Figure 17.6 A bat uses sound echoes to find its way about and to catch prey. The loud noise you create by cracking a whip occurs because the tip is moving. Figure 17.6 shows how a bat uses the speed of sound to sense distances. The speed of sound is around 1,230 kilometres per hour (or 767 miles per hour). At 0 C, the speed of sound is 331 m/s, whereas at 20.0 C, it is 343 m/s, less than a 4 increase. For example, heres how to convert 5 speed of sound to feet per. The equivalent SI unit is the metre per second.Ĭonversion calculator for all types of measurement units. While not negligible, this is not a strong dependence. The speed in feet per second is equal to the speed in speed of sound multiplied by 1,125.328084. Sound Intensity - Acoustic power of sound per unit area. Abbreviations include ft/s, ft/sec and fps. Speed of sound in air at standard atmospheric pressure with temperatures ranging -40 to 1000 o C (-40 to 1500 o F) - Imperial and SI Units. When lightning strikes, a bright flash of light is generated. We can use this knowledge to approximately determine how far away a lightning strike has occurred. You can do the reverse unit conversion fromįeet per second to speed of sound, or enter any two units below: Enter two units to convert From:įeet per second is a unit of speed it expressses the number of feet (ft) traveled in one second (s, or sec). On a standard day at sea level static conditions, the speed of sound is about 760 mph, or 1100 feet/second.
