Common Weight Conversion Formulae

Use these standard weight conversion formulas based on SI units, conversion factors, and accepted measurement standards for accurate results.

Kilograms to Pounds

Formula

Pounds=Kilograms×2.20462 \text{Pounds}=\text{Kilograms}\times2.20462

Example

10 kg×2.20462=22.0462 lb 10\ \text{kg}\times2.20462=22.0462\ \text{lb}

Pounds to Kilograms

Formula

Kilograms=Pounds2.20462 \text{Kilograms}=\frac{\text{Pounds}}{2.20462}

Example

50 lb÷2.20462=22.68 kg 50\ \text{lb}\div2.20462=22.68\ \text{kg}

Grams to Kilograms

Formula

Kilograms=Grams1000 \text{Kilograms}=\frac{\text{Grams}}{1000}

Example

2500 g÷1000=2.5 kg 2500\ \text{g}\div1000=2.5\ \text{kg}

Kilograms to Grams

Formula

Grams=Kilograms×1000 \text{Grams}=\text{Kilograms}\times1000

Example

3.2 kg×1000=3200 g 3.2\ \text{kg}\times1000=3200\ \text{g}

Grams to Ounces

Formula

Ounces=Grams÷28.3495 \text{Ounces}=\text{Grams}\div28.3495

Example

500 g÷28.3495=17.64 oz 500\ \text{g}\div28.3495=17.64\ \text{oz}

Ounces to Grams

Formula

Grams=Ounces×28.3495 \text{Grams}=\text{Ounces}\times28.3495

Example

8 oz×28.3495=226.80 g 8\ \text{oz}\times28.3495=226.80\ \text{g}

Pounds to Ounces

Formula

Ounces=Pounds×16 \text{Ounces}=\text{Pounds}\times16

Example
