Typically tempo is given in Beats-per-minute, while the SI unit would be Hz (Beats/second) but it's just a matter of dividing or multiplying by 60 to convert one to the other and minutes are anyway not more Imperial than they are Metric, so in short I have not answered you questions, you are very welcome.
Is a beat a metric or Imperial unit?
