- Kilograms (kg) = 120 × 6.35029
- Kilograms (kg) = 762.03
What are stones?
The stone (st) is a British unit of mass traditionally used in the UK and Ireland, primarily for measuring body weight. One stone is equal to 14 pounds (lbs) or approximately 6.35 kilograms (kg). Historically, the stone varied in weight depending on the commodity being measured, but the standardized version (14 lbs) was officially adopted in 1835. While no longer used in formal trade, the stone remains a common unit for personal weight measurement in the UK. It is rarely used outside these regions, as most countries have adopted the metric system, where kilograms are the standard.

What are kilograms?
The kilogram (kg) is the base unit of mass in the International System of Units (SI) and is widely used worldwide for measuring weight and mass. One kilogram is equal to 1,000 grams (g) or approximately 2.20462 pounds (lbs). Originally defined as the mass of one liter of water, the kilogram was later standardized using a physical prototype. However, in 2019, its definition was revised to be based on fundamental physical constants, specifically Planck’s constant, ensuring greater accuracy. Kilograms are essential in everyday life, used in commerce, science, industry, and health to measure everything from food ingredients to body weight and industrial materials.
