The unit “stone” is a British Imperial and customary unit of mass equivalent to 14 pounds. Therefore, a weight of 28 stones represents 392 pounds (28 x 14 = 392). This measurement is commonly used in the United Kingdom and Ireland for body weight.
Understanding this unit provides valuable context when interpreting health information, particularly concerning body mass index (BMI) and weight management programs originating in these regions. Historically, the stone’s usage traces back to the wool trade, where stones represented standardized units for weighing fleeces. Its continued use in measuring human body weight reflects cultural tradition.
