Only in that frequency is the inverse of period - and is therefore a
1/time unit.

 length <-> meter
 time <-> second
 speed <-> meters/second
 frequency <-> /second

When you're doing dimensional analysis, you may multiply a length by a
frequency to get a speed - for example, the wavelength of a particular
radio band times its frequency should give you the speed of light.
