Weight Conversion Formulas Explained
The calculator works using standard mathematical conversion formulas. To ensure accuracy, all conversions are first converted into a base unit (kilogram), and then converted into the desired unit.
1. Convert to Kilogram (Base Unit)
- Kilogram to Kilogram:
kg = kg - Gram to Kilogram:
kg = g ÷ 1000 - Pound to Kilogram:
kg = lb × 0.453592 - Ounce to Kilogram:
kg = oz × 0.0283495
2. Convert from Kilogram to Other Units
- Kilogram to Gram:
g = kg × 1000 - Kilogram to Pound:
lb = kg ÷ 0.453592 - Kilogram to Ounce:
oz = kg ÷ 0.0283495
Example Conversions
To better understand how the tool works, here are some practical examples:
Example 1: Kilogram to Pound
If you convert 5 kg to lb:
5 × 2.20462 = 11.023 lb (approx.)
Example 2: Gram to Kilogram
If you convert 2500 g to kg:
2500 ÷ 1000 = 2.5 kg
Example 3: Pound to Gram
If you convert 10 lb to g:
10 × 453.592 = 4535.92 g
Example 4: Ounce to Kilogram
If you convert 16 oz to kg:
16 × 0.0283495 = 0.4536 kg (approx.)
Conversion Table (Quick Reference)
| From Unit | To Unit | Formula | Example Result |
|---|---|---|---|
| 1 kg | g | × 1000 | 1000 g |
| 1 kg | lb | ÷ 0.453592 | 2.20462 lb |
| 1 kg | oz | ÷ 0.0283495 | 35.274 oz |
| 1 g | kg | ÷ 1000 | 0.001 kg |
| 1 lb | kg | × 0.453592 | 0.4536 kg |
| 1 oz | kg | × 0.0283495 | 0.02835 kg |
This table is especially useful for quick manual reference without calculation.
