"I was doing 70 down the highway" is absolutely the sort of thing people say. From context (this conversation takes place in the US, most highways have a speed limit somewhere around 60-70mph) people understand that you are talking about miles per hour.

KSP measures funds in some unitless value, it drives me nuts. Everything else is almost (but not quite) perfect.

Maybe you can say "6 dbm/s"
