Can propagation speed be measured in bits per second?

[sheikhimu]

In networking, propagation speed is usually measured in meters per second. If we knew how many bits fit in a meter we could multiply these values and end up with a measurement in bits per second. Does such a unit make sense?

"Does such a unit make sense?"

I don't see how it would.

How/why you think it would be of benefit?
