For example, to convert 80 kg to pounds: 80 × 2.20462 = 176.37 lbs. Our converter performs this calculation instantly with precision to four decimal places.

Understanding Kilograms and Pounds

The kilogram (kg) is the base unit of mass in the International System of Units (SI). It was originally defined in 1795 as the mass of one liter of water. Since 2019, the kilogram is defined using the Planck constant, making it the last SI base unit to be redefined in terms of fundamental physical constants.

The pound (lb) is a unit of weight in the imperial and United States customary systems. The abbreviation "lb" comes from the Latin "libra," which was a Roman unit of measure. The avoirdupois pound, which is the pound used in everyday commerce, is legally defined as exactly 0.45359237 kilograms.

History of the Kilogram

The kilogram has a fascinating history. Originally defined in 1799 by a physical platinum artifact known as the "International Prototype of the Kilogram" (IPK) stored in Sèvres, France, the kilogram was the last SI unit defined by a physical object. In November 2018, representatives from 60 countries voted to redefine the kilogram in terms of the Planck constant, a fundamental constant of quantum mechanics. This new definition took effect on May 20, 2019, ensuring the kilogram's stability for all time without reliance on a physical artifact.
