# LBS to KG Converter

When it comes to weight conversions, having an lbs to kg converter can be a lifesaver. Especially for those who frequently need to toggle between these two units of mass in their daily life or work. But what exactly are these units? And how do they convert into one another? Read on to find the answers. You can also convert vise versa using kg to kbs converter.

## Understanding the Units

### The Pound (lb)

#### Definition

The pound (symbol: lb) is a unit of mass used in the imperial and US customary systems of measurement. It is defined as exactly 0.45359237 kilograms. This avoirdupois pound has 16 avoirdupois ounces.

#### History and Origin

The pound originated from the Roman libra and saw numerous variations prior to the international avoirdupois pound used today. The avoirdupois system, first used in the 13th century, is based on a physical standardized pound that used a prototype weight divisible into 16 ounces.

#### Current Use

In the United States, the pound is widely used as a unit of weight, particularly for measuring body weight. It is also used in the UK, although less frequently due to the prevalence of the International System of Units.

### The Kilogram (kg)

#### Definition

A kilogram (symbol: kg) is the base unit of mass in the International System of Units (SI). It is currently defined based on the fixed numerical value of the Planck constant. The changes made to the definition in 2019 didn’t alter the size of the unit but were intended to improve the definitions of SI base units.

#### History and Origin

The term kilogram was derived from the French “kilogramme,” which in turn came from Greek and Late Latin terms meaning “a thousand” and “a small weight” respectively. The kilogram was initially defined as the mass of one liter of water at its freezing point, but this was later changed due to the impreciseness and cumbersomeness of the initial definition.

#### Current Use

As a base unit of SI, the kilogram is used globally in almost all fields, with the exception of countries like the United States, where it is not extensively used in everyday applications.
