The Basics of Weight Measurement Units
What is a Pound?
The pound (abbreviated as lbs) is a unit of weight commonly used in the United States and a few other countries. Its origins trace back to Roman times, but today, it is primarily used in the imperial and customary systems. One pound is defined exactly as 0.45359237 kilograms, based on the international agreement established in 1959.
What is a Kilogram?
The kilogram (abbreviated as kg) is the base unit of mass in the International System of Units (SI). It is widely used worldwide for scientific, medical, and everyday measurements. Unlike pounds, the kilogram is a metric unit and is defined based on a physical constant—the Planck constant—making it a precise and universal standard.
