About Stone (st)
The stone (st) is a unit of weight equal to 14 pounds (approximately 6.35 kg), used almost exclusively in the United Kingdom and Ireland for expressing human body weight. A person weighing 70 kg is approximately 11 stone. The stone is rarely used outside body weight — commercial goods, food, and science all use kilograms in the UK. The stone is not part of the metric system and has no formal SI equivalent; its continued use is a cultural habit, particularly in older generations and media coverage of boxing and fitness.
Average UK adult body weight is often quoted as 11–13 stone. A jockey must typically weigh under 8.5 stone to compete.
Etymology: From the practice of using actual stones as counterweights on balance scales. Standardised in England at 14 pounds by the Weights and Measures Act 1835.
About Gram (g)
The gram (g) is the fundamental practical unit of the metric system for everyday weights, defined as one thousandth of the kilogram — itself the SI base unit of mass. The gram is the standard unit for food ingredients, postal weights, and laboratory measurements. It was historically defined as the mass of one cubic centimeter of water at 4°C, a relationship that still holds approximately. The gram is small enough for precision in cooking and chemistry while being a convenient step between the milligram (pharmaceutical) and kilogram (everyday weight) scales.
A standard paperclip weighs about 1 g. A AA battery weighs roughly 23 g. A slice of bread is about 30 g.
Etymology: From the Late Latin "gramma" and Greek "grámma" (small weight), originally a unit used in apothecary measurement. Adopted by the French metric system in 1795.
Stone – Frequently Asked Questions
How many pounds are in a stone?
One stone equals exactly 14 pounds. A person who weighs 10 stone weighs 140 pounds (63.5 kg). To convert stone to kilograms, multiply by 6.35; to convert to pounds, multiply by 14.
Do people outside the UK use stone for weight?
Stone is used in the UK and Ireland for body weight but is virtually unknown elsewhere. Australians, Canadians, and New Zealanders — who all once used it — have largely switched to kilograms. Americans use only pounds. If you quote your weight in stone outside the British Isles, expect blank looks.
Why is a stone 14 pounds?
The stone historically varied between 8 and 26 pounds depending on the commodity (wool, meat, cheese). The 14-pound standard was established by the English Weights and Measures Act of 1835, partly because 14 divides evenly into the 28-pound quarter and the 56-pound half-hundredweight.
Is stone used in medical settings in the UK?
The NHS officially uses kilograms in clinical contexts, and most medical equipment is calibrated in kg. However, many patients still report their weight in stone, so UK healthcare professionals routinely work in both systems. Obesity classifications (BMI categories) are always calculated in kilograms.
How do I convert my weight from kilograms to stone and pounds?
Divide your weight in kg by 6.35 to get stone. The whole number is your stone value; multiply the decimal remainder by 14 to get the remaining pounds. Example: 75 kg ÷ 6.35 = 11.81 stone → 11 stone and (0.81 × 14) ≈ 11 lbs, so 75 kg ≈ 11 stone 11 lbs.
Gram – Frequently Asked Questions
How many grams are in an ounce?
One avoirdupois ounce equals exactly 28.3495 grams. For rough mental arithmetic, 28 g per ounce is commonly used. A 100 g weight is approximately 3.5 oz.
What weighs exactly 1 gram?
A standard US dollar bill weighs almost exactly 1 gram (1.0 g). A paperclip is approximately 1 g. A cubic centimeter of water weighs 1 g at 4°C — the original definition of the gram.
What is the difference between a gram and a gramme?
"Gram" and "gramme" refer to the same unit. "Gramme" is the French-derived spelling used in the UK and Commonwealth countries; "gram" is the US and international standard spelling. Both are correct; "gram" is more common in scientific writing and on nutrition labels worldwide.
How many grams of protein should I eat per day?
The general recommendation for sedentary adults is 0.8 g of protein per kilogram of body weight per day. For a 70 kg adult, that is 56 g/day. Athletes and those building muscle are often advised to consume 1.2–2.0 g per kg, or 84–140 g/day for the same 70 kg person.
Why is gold priced per gram but other metals per kilogram?
Gold is dense and extremely valuable relative to its volume — a kilogram of gold is worth tens of thousands of dollars, making grams a more practical transaction unit. Precious metals (gold, silver, platinum) are also traded in troy ounces (31.1 g). Industrial metals like copper or steel are cheap enough that pricing per kilogram or tonne is more practical.
