> Although there's a popular simplified model that expresses an ideal weight as a function of kg/m^2, the weight/height ratio is indeed expressed as kg/m. That's a non-sequitur argument: the OP wasn't talking about height/mass ratio. BMI is clearly defined and it is not weight/height ratio.[0] You might as well have said "I think the units for BMI are indeed kg/m, because Abraham Lincoln was born in 1809".
