Q: What is 81kg in stone and lb?

The correct answer is: $81\text{ kg}=12\text{ st }10.6\text{ lb}\ (\approx178.57\text{ lb})$ Explanation Convert kilograms to pounds, then convert pounds to stones (1 stone = 14 lb). Steps: Convert to pounds: $$178.5744323658\text{ lb}=81\times2.2046226218\text{ lb}$$ Find whole stones: $$\text{stones}=\left\lfloor\frac{178.5744323658}{14}\right\rfloor=12$$ Pounds remaining: $$\text{pounds remaining}=178.5744323658-12\times14=10.5744323658\text{ lb}\approx10.6\text{ lb}$$ Therefore, 81 kg ≈ 12 st 10.6 lb (which is about 178.57 lb).
