Why do four formulas give four different weights?
For the same man at 175 cm the four published rules of thumb give 72.0 kg, 70.5 kg, 68.9 kg and 68.7 kg — 3.3 kilos between the highest and the lowest. They were drawn up for working out drug doses, which is why the page shows a range and never a target.
