Convert Stone and Pounds to Kilograms
In the UK and Ireland, body weight is often measured in stone and pounds. While this system is popular in British culture, the metric system uses kilograms. Understanding how to convert between the two is essential, especially for fitness, travel, or medical purposes.
What Is a Stone and Pound?
In the UK, weight is often measured using stones and pounds, especially when referring to body weight. This traditional system is still commonly used and understood by many.
One stone is equal to 14 pounds (approximately 6.35 kilograms).
For example, if someone says they weigh “11 stone 4,” it means 11 stones and 4 pounds — or 158 pounds in total.
It’s a gentle and familiar way of expressing weight that many find more relatable than kilograms alone.
On a slightly different note, when we talk about stone in a practical or home context, such as stone worktops, we’re referring to the natural material itself. Stone worktops — made from materials like granite, quartz, or marble — are highly valued in British kitchens for their durability, beauty, and timeless appeal.
So, while “stone” can mean a unit of weight, it also represents strength and elegance in our homes — especially when it comes to crafting beautifully made stone worktops.
