Sometimes I read about feed rates and they are most likely not expressed in the units I accustomed to.
For example someone might say the recommended feed rate for such and such material is 22 mm/min. Well how much is that in in/sec?
For this reason I created the Feed Rate conversion calculator. I have made it public and can be accessed at:

Give it a try, you might find it useful.
