The speed of sound, at 20° C in dry air at sea level, is 343.2 m/s, for 0.3432 m/ms.

Then the distance multiplied by the speed of the sound in M/S right?

if you know distance in m, divide by the speed of sound in m/s to get time delay in s. For a distance of 3 m, (3 / 343.2) = 0.00874 sec., or 8.74 ms.

if you know time delay in s, multiply by the speed of sound in m/s to get distance in m. For a time delay of 8.74ms, (0.00874 x 343.2) = 3 m.

For the casual/sloppy, figure that 1foot is equivalent to 1second.

1 foot = 1 millisecond I think you meant...
