Kilograms to Pounds (KG to LBS) and Pounds to Kilograms (LBS to KG) – Everything You Need to Know
Weights and measurements are part of everyday life, but sometimes it’s confusing when different countries use different systems. Two of the most common weight units are kilograms (kg) and pounds (lbs). Understanding how to convert between them is useful for cooking, fitness, shipping, or just general knowledge.
What is a Kilogram?
A kilogram (kg) is a unit of mass in the metric system, which is used by most countries around the world.
- 1 kilogram is equal to 1,000 grams.
- The metric system is based on powers of ten, which makes it easy to calculate.
- Kilograms are commonly used in Europe, Asia, and Africa for things like measuring body weight, groceries, and luggage.
What is a Pound?
A pound (lb) is a unit of mass in the imperial system, mainly used in the United States, Liberia, and Myanmar.
- 1 pound is equal to 16 ounces.
- Pounds are often used to measure body weight, packaged food, and postal items in the US.
💡 Fun fact: The abbreviation “lb” comes from the Latin word libra, which was a unit of weight in ancient Rome.
How to Convert KG to LBS
The easiest way to convert kilograms (kg) to pounds (lbs) is:
lbs = kg × 2.20462
Example:
If you weigh 70 kg:
70 × 2.20462 = 154.32 lbs
So, 70 kg is roughly 154 lbs.
How to Convert LBS to KG
To convert pounds (lbs) back to kilograms (kg), use:
kg = lbs ÷ 2.20462
Example:
If an item weighs 200 lbs:
200 ÷ 2.20462 ≈ 90.72 kg
So, 200 lbs is about 91 kg.
