Conversion Formula Explained

The calculator uses the following formula to ensure correct results: Kilograms (kg)=Pounds (lb)×0.45359237\text{Kilograms (kg)} = \text{Pounds (lb)} \times 0.45359237Kilograms (kg)=Pounds (lb)×0.45359237

To get grams, the kilograms result is multiplied by 1000: Grams (g)=Kilograms (kg)×1000\text{Grams (g)} = \text{Kilograms (kg)} \times 1000Grams (g)=Kilograms (kg)×1000

For example:

• 10 lb × 0.45359237 = 4.5359237 kg
• 4.5359237 × 1000 = 4535.9237 g
