Please add the speed in meters per second, most countries dont use imperial units.

I truly appreciate a detailed answer!! Thank you, but I do agree with Phytime. Meters should be included to cover all counties. Sadly, in America, we do not use the measurement of meters more often.

I knew the velocity in air but did not know how much faster it traveled in other media. always something new to learn.

Phytime, someone must have edited it, because they now have metric measurements.

Timbo, I am American, and I would love if the USA would change to metric. It is difficult to mentally multiply by 12, or 16, or 5280. Geez.

how about we put scientific fact in metric? Freedom units have to go the way of the dinosaur already.

I was under the impression that barometric pressure was a factor too. How fast do you think sound travels at a specific temp and humidity if there is hardly any air, such as if comparing 25000 ft (7620 m) to sea level?
