Also, as far as metabolic rate is concerned, the metric unit is 
universally accepted. In imperial units, metabolic rate is often 
calculated technically as MET (metabolic equivalent), but 1 /MET/ = 3.5 
ml O2/kg/min, which brings us back to the metric unit. The unit of ml 
O2/kg/min is referred to as the VO2. I have never seen VO2 expressed in 
imperial measures, principally because there is not a direct and 
scale-equivalent analog of ml in imperial units (cu ft is not useful 
here). There is a reasonable explanation in the Wikipedia articles on 
VO2. and MET.

Overall, I think we are reasonably safe.

Kind regards,
willem
