A note on rounding
Conversions are shown rounded for readability, weights to a tenth of a unit, heights to the nearest inch or centimetre. The underlying arithmetic uses the full precision of the internationally defined factors, so repeatedly converting back and forth will not drift.
Bathroom scales themselves are usually accurate to within a few hundred grams at best, and body weight varies by a kilogram or more across a single day. That variation is far larger than any rounding here.
