Weight converter formula (lbs, kg)

Pound in Kilograms

Pound (lbs) / 2.2046 = Result in Kilograms (kg)

Kilograms to pound

Kilograms (kg) x 2.2046 = Result in Pound (lbs)

Weight Conversion Example

100 pounds (lbs) / 2.2046 = 45,36 kilos (kg)

100 kilos (kg) * 2.2046 = 220,46 pounds (lbs)

The pound

This unit of mass measurement is converted into kilograms according to the Imperial pound (453,59237g). Note that some countries converted the pound in a different way, such as:

Country Conversion into gram (s) (g = 0.001kg or 1000g = 1kg)
Germany, Austria, Denmark, Switzerland 500g (0.5kg)
Russia (the Russian pound obsolete) 425,076g (0.425076kg)
Norway 498,1g (0.4981kg)

This weight unit was called metric pound which in the past was between 0.380kg and 0.552kg but has a modern value of 500 grams.

However, the pound or imperial pound (adopted in 1878 in the United Kingdom) as well as the metric pound as we know today are closer to the Paris pound or 0.4895kg than the one used by the Romans.

The Roman pound (libra), equivalent to 324g to 329g, is largely different in terms of imperial comparison compared to the Roman unit (in ancient Greece), the Attic mina (100 drachmae), which was equivalent to approximatly 0.432kg to 0.4366kg.

This last Roman weight unit was used to define the abbreviation we know today either lb or lbs (for libra in Latin).
