Do you mean 47 kilograms (kg) or 47 pounds (lb)?
If you mean 47 kilograms:
- 47 kg = $47\times2.20462262=103.617263\text{ lb}$
- Stones: $\lfloor103.617263/14\rfloor=7$ stones, remainder $103.617263-7\times14=5.617263\text{ lb}$
- So 47 kg ≈ 7 st 5.6 lb (about 7 st 6 lb if rounded to the nearest pound).
If you mean 47 pounds:
- $47\div14=3$ remainder $5$
- So 47 lb = 3 st 5 lb.
