Actually. The conversion doesn't work.

The requests per minute number is an average.

The requests per second number should be given for peak load. That is a very important metric, a system has to be scaled to sustain the peaks, not the average.

We'd need to know the traffic pattern to know the multiplier, that is certainly not 60 :p

Units per minute gives you a lower bound on units per second. You can't reach an average of X/min without achieving at least (X/60)/sec.
