No need to panic, John!
The virtual CrCl formula incorporates the empirical, statistical finding
that:
Creatinine Output is proportional to weight * (140-age)
The proportionality constant itself has units eg mmol/(24hr*Kg*Year).
Putting in the 1440 mins in 24 hrs results in your factor of 1.2
On your second point I seem to remember that decimalisation of the UK
currency nearly 30 years ago was to be followed by a rapid programme of
metrication. Yet we've still managed to hang on to our pints of warm
British beer!
