About Weight Conversion
Weight (or more precisely, mass) conversion is essential in cooking, science, shipping, health, and countless other fields. The metric system uses grams and kilograms as its primary units, while the imperial system relies on ounces, pounds, and stones. Understanding how to convert between these systems is crucial in our interconnected world.
The kilogram is the SI base unit of mass and is defined by the Planck constant as of 2019, replacing the original physical artifact kept in France. One kilogram equals approximately 2.205 pounds. The stone (14 pounds) is commonly used in the UK and Ireland for body weight.
This converter handles everything from tiny milligram measurements used in pharmaceuticals to metric tons used in industrial shipping, providing precise results for any weight conversion you need.
