Stone to Pounds Converter
Understanding the link between the stone and the pound is essential, especially in regions like the United Kingdom where both units of mass are still in everyday use. While most countries use kilograms, the stone to pounds converter remains a quick and reliable way to measure body weight or compare across systems.
Stone
The stone (st) is part of the English and imperial system, officially defined as 14 pounds or 6.35029318 kilograms. In antiquity, people used real stones as weights in trade across England and northern Europe.
By 1350, the stone was standardised for wool at 14 pounds, and in 1835, the United Kingdom fixed this value in the imperial system. Today, its current use is mostly tied to body weight, making it familiar in the UK, while most other countries rely on kilograms or pounds.
Pound
he pound (lb) belongs to both the imperial and US customary systems of measurement. The widely accepted international avoirdupois pound equals 0.45359237 kilograms or 16 ounces.
The history traces back to the Roman libra, with many definitions evolving over time. The avoirdupois system took hold in the 13th century, and by 1959, the modern form was adopted, based on a prototype weight. Its ease of division into 16 ounces with simple divisors like 8, 4, and 2 made it more practical than systems that used 10, 12, or 15 subdivisions.
In current use, the pound dominates in the United States, particularly for body weight. In the UK, although the International System of Units is standard, pounds remain in use for packaged foods and alongside stones when referring to body weight.
How to Convert Stones to Pounds
