Speed of sound is speed unit, symbol: [s]. Definition of 1 speed of sound ≡ (1.4 x 286 x (20+273.15) )-2. Speed of sound in the air. But this speed varies between 295-340 m/s depending on the air temperature and pressure. From the NASA formula I calculated the speed on sea level at 20°C.. Compared to metre per second, speed of sound is bigger unit.

• 1 [s] = 342.603648550333 [m/s]

• 1 [m/s] = 1/(342.603648550333) [s] = 0.0029188247242297 [s]
