Understanding Pounds and Kilograms
What is a Pound?
The pound (abbreviated as lb) is a unit of weight primarily used in the United States and a few other countries. It has historical roots dating back to Roman times and has evolved over centuries. Today, the pound is part of the imperial and US customary measurement systems.
Key facts about pounds:
- 1 pound equals 16 ounces.
- The pound has different definitions in various systems, but the most common international standard is the avoirdupois pound.
What is a Kilogram?
The kilogram (kg) is the base unit of mass in the International System of Units (SI). It is widely adopted globally for scientific, industrial, and everyday measurements.
Key facts about kilograms:
- 1 kilogram equals 1,000 grams.
- It was originally defined in 1795 as the mass of one liter of water, but its current definition is based on a physical constant—the Planck constant.
