Unit definitions
What is a gram (g)?
The gram, abbreviated as "g," is the metric system’s base unit for mass. Think of it as the lightweight champion: a paperclip weighs about 1 gram. Officially, it’s one-thousandth of a kilogram. You’ll spot grams everywhere—on nutrition labels, in lab measurements, and even in your morning coffee grounds.

What is a stone (st)?
The stone (st) feels like a relic but thrives in British daily life. One stone equals 14 pounds or 6.35029 kilograms. Originally used for trading goods like wool, it’s now mostly reserved for personal weight. If someone says they’ve lost "half a stone," that’s roughly 3.175 kilograms—a significant milestone!

Conversion formula
To swap grams for stones, divide the gram value by 6350.29. Why that number? Because one stone is precisely 6350.29 grams. Here’s the formula in action:
Stones = Grams ÷ 6350.29
For example:
- 5000 grams to stones: 5000 ÷ 6350.29 ≈ 0.787 st
- 10,000 grams to stones: 10,000 ÷ 6350.29 ≈ 1.5747 st
Reverse the math to convert stones back to grams: multiply by 6350.29. Easy peasy.

Historical background
The gram’s origin story starts with the French Revolution. In the 1790's, scientists sought a “natural” unit of mass, defining the gram as the weight of one cubic centimeter of water. The stone, meanwhile, has wilder roots. Medieval Europe used stones ranging from 5 to 40 pounds depending on the traded goods. Britain standardized it to 14 pounds in 1835, but the EU’s metric push nearly phased it out by 1985. Yet, like a stubborn phoenix, it remains a cultural icon.
