Understanding Weight Units: Pounds and Kilograms
What is a Pound (lb)?
The pound, symbolized as lb, is a unit of weight commonly used in the United States, the United Kingdom, and some other countries. It originates from the Roman libra, a unit of measure used in ancient Rome. In modern times, the pound is part of the imperial system of measurement, which is still prevalent in some regions.
Key facts about pounds:
- 1 pound equals exactly 16 ounces.
- It is primarily used for measuring body weight, food, and other small to medium weights.
- The pound is a customary unit and is not part of the SI (International System of Units).
What is a Kilogram (kg)?
The kilogram is the base unit of mass in the SI system, the internationally accepted system of measurement. It is widely used worldwide for scientific, industrial, and everyday measurements.
Key facts about kilograms:
- 1 kilogram equals 1,000 grams.
- It is used globally, including in scientific contexts, for measuring body weight, goods, and more.
- The kilogram was originally defined by a physical artifact—the International Prototype Kilogram—but now is defined by fundamental constants.
