Sound travels at 331.3 m/s: an echo returning after 1 second comes from 165.7 m away, and thunder takes 24.29 s to cross 5 miles.
What it means
How warm is that air?
Dry air, ideal gas: 331.3 √(1 + T/273.15) m/s. Humidity adds up to about 0.5 %; pressure has no effect.
The math
How to convert °C to km/h
c = 331.3 × √(1 + T ÷ 273.15) m/s; T = 273.15 × ((c ÷ 331.3)² − 1).
Example: 0 °C = 1,192.68 km/h.
