Kilogram to Stones Converter (kg to st) | Kg to St Formula, Table

Understanding units of weight measurement is a skill that everyone should have. Especially if we are using these units in our day-to-day life. Granted, that understanding the relationship between these units can get confusing at times. Therefore, we are here to help you to get some clarity over the conversion of Kilogram to Stones. So, in this blog, we will talk about the origin and meaning of kilogram and stone. We will also discuss the process of converting kilogram to stone, and the formula for doing the same. 

Let’s begin to understand the basics of Kilogram to Stones conversion!

What is a Kilogram?

The kilogram can be defined as a base unit for measuring mass in the International System of Units. This unit is widely denoted by the symbol ‘kg’. The word kilogram is derived from the French word ‘kilogramme’, which in turn was coined by prefixing the Greek term ‘khilioi’ to the 

Latin term for small weight, namely ‘gramma’. 

The 1795 definition of kilogram states kilogram to be equivalent to the mass of one liter of water. The Kilogramme des archives later swapped this definition as the standard for mass in 1799. A platinum-iridium cylinder later became the standard for the unit of mass in 1889. The current definition of a kilogram is based on nature’s fundamental constants. This helps the scientific community for the calibration of various scientific instruments. 

What are Stones?

A stone or stone weight is an imperial unit of mass that is roughly equivalent to 14 pounds. This unit is still widely used in the UK for the measurement of weight and was formerly used in European countries for trade, with values ranging up to 40 pounds. The onset of the 19th century meant that this unit was eventually replaced by the ‘kilogram’. 

Before the implementation of the metric system, this unit was used in many European countries. The value of 1 stone varied from country to country but was usually around 3 to 10 pounds. During the 19th century, European states like Netherlands and Southwestern German states, redefined this unit to make it in sync with the kilogram.
