Understanding the Conversion Formula
Each conversion is based on a fixed mathematical formula. The calculator uses standard internationally accepted conversion constants.
Weight Conversion
Kilogram to Pound:
1kg=2.20462lb
Formula:
- Pounds = Kilograms × 2.20462
Pound to Kilogram:
1lb=0.453592kg
Formula:
- Kilograms = Pounds × 0.453592
Length Conversion
Centimeter to Inch:
1cm=0.393701in
Formula:
- Inches = Centimeters × 0.393701
Inch to Centimeter:
1in=2.54cm
Formula:
- Centimeters = Inches × 2.54
Distance Conversion
Kilometer to Mile:
1km=0.621371mi
Formula:
- Miles = Kilometers × 0.621371
Mile to Kilometer:
1mi=1.60934km
Formula:
- Kilometers = Miles × 1.60934
Example Calculations
Example 1: Kilogram to Pound
You want to convert 5 kg to pounds:
5 × 2.20462 = 11.0231 lb
✔ Result: 5 kg = 11.0231 lb
Example 2: Centimeter to Inch
Convert 100 cm to inches:
100 × 0.393701 = 39.3701 inches
✔ Result: 100 cm = 39.3701 in
Example 3: Kilometer to Mile
Convert 10 km to miles:
10 × 0.621371 = 6.2137 miles
✔ Result: 10 km = 6.2137 mi
