Everything routes through the kilogram
Like the inch, the pound has been exactly defined since 1959: 1 lb = 0.45359237 kg. Sixteen ounces make a pound; fourteen pounds make a stone (the UK's body-weight unit); and "ton" is three different things, the metric tonne (1,000 kg), the US short ton (2,000 lb) and the UK long ton (2,240 lb).
75 kg ≈ 165.3 lb ≈ 11 st 11.3 lb
Quick mental swaps
Kilos to pounds: double it and add 10% (75 → 150 + 15 = 165). Ounces to grams: multiply by 28. Technically these are units of mass, not weight, but on Earth's surface the everyday usage is fine. Baking in cups instead of grams? The cups-to-grams converter handles volume-to-weight, which needs ingredient density.
