Complete Weight Conversion Guide
This guide covers all major weight conversions including kilograms, grams, milligrams, pounds, ounces and tons. You will find formulas, examples, tables, and everyday applications—perfect for students, fitness, cooking, science, shipping and engineering.
Kilogram to Gram (KG → G)
Grams are used for small objects, cooking and science experiments. 1 kilogram = 1000 grams.
Formula
Grams = Kilograms × 1000
Example
2.5 kg × 1000 = 2500 g
| KG | G |
|---|---|
| 1 | 1000 |
| 5 | 5000 |
| 10 | 10000 |
Gram to Kilogram (G → KG)
Used for converting small measured values into larger units.
Formula
Kilograms = Grams ÷ 1000
Example
2500 g ÷ 1000 = 2.5 kg
Kilogram to Milligram (KG → MG)
Milligrams measure extremely small quantities such as medicine dosages.
Formula
Milligrams = Kilograms × 1,000,000
Example
0.002 kg × 1,000,000 = 2000 mg
Milligram to Kilogram (MG → KG)
Formula
Kilograms = Milligrams ÷ 1,000,000
Example
500,000 mg ÷ 1,000,000 = 0.5 kg
Kilogram to Pound (KG → LB)
Pounds are commonly used in the US for body weight, fitness, shipping and grocery items.
Formula
Pounds = Kilograms × 2.20462
Example
70 kg × 2.20462 = 154.32 lb
Pound to Kilogram (LB → KG)
Formula
Kilograms = Pounds ÷ 2.20462
Example
150 lb ÷ 2.20462 = 68.03 kg
Ounce to Gram (OZ → G)
Formula
Grams = Ounces × 28.3495
Example
10 oz × 28.3495 = 283.49 g
Gram to Ounce (G → OZ)
Formula
Ounces = Grams ÷ 28.3495
Example
200 g ÷ 28.3495 = 7.05 oz
Ton to Kilogram (TON → KG)
Formula
Kilograms = Tons × 1000
Example
2 tons × 1000 = 2000 kg
