When it comes to measuring body weight, different regions of the world use various units of measurement. For instance, kilograms (kg) are widely used in most countries that have adopted the metric system, while stones are a popular unit in the United Kingdom and Ireland. Converting between these units can be confusing for those unfamiliar with the process. One commonly searched conversion is “67 kg in stone.”
In this article, we will explore how to convert kilograms to stones, the history behind these units, and answer common questions that people search for on Google and YouTube.
What Is a Kilogram?
A kilogram (kg) is the base unit of mass in the International System of Units (SI), the modern form of the metric system. It is defined as being equal to the mass of the International Prototype of the Kilogram, a platinum-iridium alloy cylinder stored by the International Bureau of Weights and Measures. The kilogram is commonly used worldwide to measure body weight, groceries, and various everyday objects.
What Is a Stone?
A stone (st) is a unit of weight that is part of the imperial measurement system, primarily used in the United Kingdom and Ireland for measuring body weight. One stone is equivalent to 14 pounds (lbs), which makes it a convenient unit for expressing body weight because it simplifies the numbers, especially for higher weights. While the stone is still commonly used for personal body weights in the UK and Ireland, other parts of the world, including the US, have largely adopted pounds or kilograms.
How to Convert Kilograms to Stones?
Converting kilograms to stones involves a simple mathematical calculation. The formula is:
Stones = Kilograms ÷ 6.35029
This formula comes from the fact that 1 stone equals 6.35029 kilograms. To find out how many stones are in 67 kg, you would perform the following calculation:
67 kg ÷ 6.35029 ≈ 10.55 stones
So, 67 kilograms is approximately 10.55 stones.
Why Do We Use Stones to Measure Weight?
The use of stones to measure weight dates back to ancient times when different regions used various standard weights for commerce, particularly for trading goods like grains or livestock. The stone was a popular unit because it was relatively large, making it suitable for everyday objects, unlike smaller units like ounces. The stone continued to be used in Britain, even after metrication began, due to tradition and ease of use when discussing personal body weight.
