Conversion Formulas

1. Pounds & Ounces to Kilograms

$$\text{Kilograms (kg)}=(\text{Pounds}\times 0.453592)+(\text{Ounces}\times 0.0283495)$$

Example Calculation

$$(8\times 0.453592)+(6\times 0.0283495)=3.628736+0.170097=3.7988\text{ kg}$$

$$5.5\times 2.20462=12.12541\text{ lbs}$$$$\text{Pounds}=12\text{ lbs}$$$$\text{Ounces}=(12.12541-12)\times 16\approx 2\text{ oz}$$
