How to Convert 108 lb to kg
The Basic Conversion Formula
The standard method to convert pounds to kilograms involves multiplying the weight in pounds by the conversion factor:
\[ \text{Weight in kg} = \text{Weight in lb} \times 0.45359237 \]
Applying this to 108 lb:
\[ 108 \times 0.45359237 = 48.995 \text{ kg} \]
Rounding to two decimal places, 108 lb is approximately 49.00 kg.
Step-by-Step Conversion Process
1. Identify the weight in pounds — in this case, 108 lb.
2. Use the accurate conversion factor — 1 lb = 0.45359237 kg.
3. Multiply the pounds by the conversion factor:
108 lb × 0.45359237 = 48.995 kg.
4. Round the result as needed, typically to two decimal places:
Approximately 49.00 kg.
