Kilogram (kg): This is the base unit of mass in the International System of Units (SI). It is defined as being equal to the mass of the International Prototype of the Kilogram (IPK), which is almost exactly equal to the mass of one liter of water.
-
Pound (lb): Known as the 'international avoirdupois pound', it's commonly used in the United States and the UK for measuring weight or mass. 1 lb is equivalent to 16 ounces or 0.45359237 kilograms.
The Conversion Formula
To convert kg to lb, you use the following formula:
**Pounds (lb) = Kilograms (kg) x 2.2046226218**

Practical Examples
Imagine you're planning to lose weight, and your goal is set in pounds, but your scale only shows kilograms. Or perhaps you're at a gym with a scale in kg, but you're used to seeing results in pounds. Here's how you could use the conversion:
-
Weight Loss: If your target is to weigh 140 lbs, you'd first convert to kilograms (140 / 2.20462 = approx. 63.50 kg), then track your progress in kilograms.
-
Gym Sessions: You lift 30 kg on a leg press machine. Knowing you need to increase to 70 kg for progress, you convert this to pounds to compare with your usual measurements.
70 kg x 2.20462 โ 154.32 lbs
