Formula
result = value × (from.toBase ÷ to.toBase)
Kilograms are the base. A pound is 0.453592 kg and an ounce is 0.0283495 kg — avoirdupois (everyday US/UK) weights, not troy ounces used for precious metals.
Worked example
100 kilograms is about 220.46 pounds — the number you'd see on a US gym scale if you stepped on at 100 kg.
Where this can give the wrong answer
- This is mass in everyday units, not force (newtons) — 'weight' on a label usually means mass unless you're doing physics homework.
- Troy ounces (31.1 g) differ from avoirdupois ounces (28.35 g); only avoirdupois is supported here.
- Stone (st) isn't listed; convert via pounds (1 st = 14 lb) if you need British body-weight units.
FAQ
- Airlines often quote both; 23 kg ≈ 50.7 lb. This calculator uses the exact conversion factor, so 23 kg comes out to 50.706 lb — rounding on signage may differ by a fraction.
