To convert kilograms to pounds we use the conversion factor $1\text{ kg} = 2.2046226218\text{ lb}$. Multiply the mass in kilograms by that factor to get pounds.
Steps:
- Conversion factor: $$1\text{ kg} = 2.2046226218\text{ lb}$$
- Multiply: $$72\text{ kg} \times 2.2046226218\frac{\text{lb}}{\text{kg}} = 158.7328287696\text{ lb}$$
- Round to a reasonable precision: $$\approx 158.73\text{ lb}$$
Therefore, $72\text{ kg} \approx 158.73\text{ lb}$.
