2. The Conversion Factor: KG to LBS
Exact Conversion Factor
The exact conversion factor from kilograms to pounds is:
1 kg = 2.20462262185 lb
This means that one kilogram is equal to approximately 2.20462 pounds. For most practical purposes, this figure is often rounded to 2.205 lb for simplicity.
Approximate Conversion Factor
For quick estimations, you can use the approximate conversion factor:
1 kg ≈ 2.205 lb
This approximation is accurate enough for everyday use and simplifies mental calculations.
3. How to Convert Kilograms to Pounds: The Formula
The Formula
To convert kilograms to pounds, you can use the following formula:
Mass in pounds (lb) = Mass in kilograms (kg) × 2.20462262185
Or, using the approximate conversion factor:
Mass in pounds (lb) ≈ Mass in kilograms (kg) × 2.205
Step-by-Step Guide
- Identify the mass in kilograms: Determine the value you want to convert from kilograms to pounds.
- Multiply by the conversion factor: Multiply the mass in kilograms by 2.20462 (or 2.205 for an approximate value).
- Calculate the result: The result is the equivalent mass in pounds.
Example Conversion
Let’s convert 15 kg to pounds using the exact conversion factor:
Mass in pounds (lb) = 15 kg × 2.20462262185
Mass in pounds (lb) = 33.06933932775 lb
Using the approximate conversion factor:
Mass in pounds (lb) ≈ 15 kg × 2.205
