The stone remains widely used in the United Kingdom and Ireland for human body weight: in those countries people may commonly be said to weigh, e.g., "11 stone 4" (11 stones and 4 pounds), rather than "72 kilograms" as in most of the other countries, or "158 pounds", the conventional way of expressing the same weight in the US and in Canada. [38]
Mass: kilograms – most typically, for newborns from about 3–4 kg (7–9 lb) for a human adult their weight range is about 50–100 kg (100–200 lb) Force: newtons (e.g. the weight of a human on Earth, on the order of several hundred newtons, or about 100–200 lb f)
Restated in mathematical terms, on the surface of the Earth, the weight W of an object is related to its mass m by W = mg, where g = 9.80665 m/s 2 is the acceleration due to Earth's gravitational field, (expressed as the acceleration experienced by a free-falling object).
Today only the stone continues in customary use for measuring personal body weight. The present stone is 14 pounds (~6.35 kg), but an earlier unit appears to have been 16 pounds (~7.25 kg). The other units were multiples of 2, 8, and 160 times the stone, or 28, 112, and 2240 pounds (~12.7 kg, 50.8 kg, 1016 kg), respectively.
Usually, the relationship between mass and weight on Earth is highly proportional; objects that are a hundred times more massive than a one-liter bottle of soda almost always weigh a hundred times more—approximately 1,000 newtons, which is the weight one would expect on Earth from an object with a mass slightly greater than 100 kilograms.

Barrel: as in many regions, varied by content: 40 [Irish] gallons for "grain" and quicklime; 12 stone for malt; 14 stone for oats; 16 stone for barley; 20 stone for beans, peas, wheat, and potatoes. [62] Stone: in Dublin was 15 pounds for rough tallow and 16 pounds for wool (instead of the standard 14 pounds). [63]
