The speed of sound in air is 332 ms-1. Is it advisable to define the length 1 m as the distance travelled by sound in 1/332 s?

No, it is not advisable to define the length 1 m as the distance travelled by sound in 1/332 s because sound is classified as a mechanical wave, meaning it requires a medium in order to travel. The speed of sound is affected by density and viscosity. These in turn are affected by temperature, pressure, composition and currents (as with wind). Therefore, it's not viable to say that the length 1 m as the distance travelled by sound in 1/332 s.
