Definition of Stone
- Definition
- The stone (st) is a traditional British unit of mass, primarily used for expressing human body weight in the UK and Ireland.
Although not part of the SI system, it remains culturally relevant and widely understood in health-related contexts. - Exact factor
- 1 st = 14 lb = 6.35029318 kg
- Examples
- • 11 st ≈ 69.85 kg
• 12 st 7 lb ≈ 79.38 kg
Definition of Gram
- Definition
- The gram (g) is a metric unit of mass equal to one thousandth of a kilogram. It is widely used for measuring small quantities, particularly in food labeling, chemistry, and laboratory work.
Although not an SI base unit, the gram is fully compatible with the SI system and remains one of the most commonly used mass units worldwide. - Exact factor
- 1 g = 0.001 kg = 0.0352739619 oz
- Examples
- • 250 g ≈ 8.82 oz
• 500 g = 0.5 kg
About the Stone
Facts & Uses
- Traditional British and Irish unit equal to exactly 14 avoirdupois pounds = 6.35029318 kg. Still in everyday use in the UK and Ireland for body weight.
- Used in healthcare records, weight-loss programs, and sports broadcasting (boxing, rugby, horse racing) — typically reported as "X stone Y pounds" (e.g., 12 st 7 lb).
- Largely obsolete in commerce — UK retail and food packaging have used metric units (kg) since the 1995/2000 EU directives — but persists culturally for personal weight.
- Not used in the United States or in continental Europe; American expatriates in the UK often find the unit confusing on their first GP visit.
Curiosities
- The name comes literally from the practice of using stones as standard weights in medieval markets. The value varied wildly by region and commodity — from 4 lb (in some wool trades) to 32 lb (for cheese in Northumberland) — until the 1835 Weights and Measures Act fixed it at 14 lb.
- A typical adult man in the UK weighs around 11–14 stone (70–89 kg); a typical woman 9–12 stone (57–76 kg).
- The plural is irregular: "He weighs 12 stone" (singular form even for plural quantity) — a quirk of British English.
- 1 st = 14 lb = exactly 6.35029318 kg ≈ 224 oz.

About the Gram
Facts & Uses
- Metric unit equal to 1/1000 of a kilogram (10⁻³ kg). Although not an SI base unit itself, it is the most widely used mass unit in everyday metric practice.
- Standard for nutrition labels worldwide (protein, carbs, fat, sodium per serving), laboratory chemistry, and European cooking recipes.
- Used in postal rates (most countries outside the US), spice and herb measurements, and illicit drug weights in legal/medical literature.
- Subdivisions: milligram (pharmaceuticals), microgram (vitamins, hormones); multiples: kilogram, tonne.
Curiosities
- Originally defined in 1795 as the mass of 1 cubic centimeter of water at 4 °C (its density maximum) — an elegant link between length, volume, and mass that survives only as an approximation today.
- A standard paperclip weighs about 1 g; a US dollar bill ≈ 1 g; a raisin ≈ 0.5 g — useful for intuiting small masses.
- 1 g ≈ 0.0353 oz ≈ 0.00220 lb ≈ 15.43 grains.
- The gram is so practical that the SI Brochure recognizes it explicitly even though kilogram is the base unit — a rare case of pragmatism over purity.
