although we use the metric system in Australia, i still mainly use the English (or Imperial, pick your poison) equivalents for height and weight. maybe IMHO it makes more “sense”, maybe it’s just a force of habit (as we use a “mixed” version in the Philippines. strangely, we’ve not committed to one nor the other), or maybe some kind of combination of these.

apparently, lb is short for the Latin libra which roughly translates to “pound weight” – this etymology is also the root of the currency.

i partly recall the jingle to fully “convert” the population to metric that’s why i remember these ratios: cm = in * 2.54; lbs = kg * 2.2…
