This BMI calculator (pre-version 1) and any other topics in the vague folder means
this BMI subject is not my expertise, just what I have learnt from Internet, another words
while there is unlikely to be a mistake however the weight limits might not be set correctly to what
professional health people use.
How this calculator come about. When I stopped growing I always thought of my height
in foot-inches, since then New Zealand has gone metric, so guess what? There are not many
calculators on Internet that works out the BMI from Foot-Inches & Kilograms.
