1 lb = 0.453592 kg (approximately equal to)
1 kg = 2.20462 lbs (approximately equal to)


We are going to convert a mass from 50 lbs to kilograms.
Mass = 50 lbs
1 lb = 0.453592 kg
Mass = 50 lbs = 50 x 0.453592 = 22.68 kg
The symbol for the pound is "lb" or "lbs" in the plural form. "lb" is the abbreviation of the Latin word "libra".

Difference between mass and weight:

Mass represents the amount of matter in a body and it is measured in kilograms for example.
Weight is the force that this body exerts on the ground and it is measured in Newtons. Weight is the measure of the amount of force acting on a mass due to the acceleration due to gravity.
The mass is the same everywhere in the Universe. It is the weight that varies.


The metric system of measurements uses the mass units kilogram (kg), gram (g) and tonne (t). Mass is used to measure the weight of an object. The standard unit of mass is kilogram and in short it is written as kg.

The seven SI base units (International System of Units) are composed of kilogram (kg) for mass, meter (m) for length, second (s) for time, kelvin (K) for temperature, mole (mol) for amount of substance, ampere (A) for electric current and candela (cd) for luminous intensity.
