Pounds to stones divides by 14. A 175 lb person is 12.5 st, spoken as 12 st 7 lb; a 154 lb adult is 11 st exactly. The whole-number part is the stones, and the remainder times 14 — wait, the remainder IS already in pounds, so 0.5 st = 7 lb. UK medical and fitness contexts expect stones-and-pounds; converting a US-stated pound weight to this format is the everyday use. Decimal stones (12.5 st) are correct on paper but rarely spoken aloud.
UK removal companies and gyms quoting to American clients or expats translate pound-based readings into the stone system locals expect — 154 lb is exactly 11 st, 200 lb is 14.29 st, and 98 lb is exactly 7 st. Multiples of 14 land on clean whole-stone figures, which is why UK weight charts are often built around 14 lb increments rather than round pound numbers; check whether a quoted "stone" figure has already dropped the pounds remainder before treating it as exact.

The international avoirdupois pound (lb) is a unit of mass in the imperial and US customary systems, defined as exactly 0.45359237 kilograms since the 1959 international yard and pound agreement. It is the everyday unit for body weight, groceries, and shipping in the United States. Sixteen ounces make one pound; fourteen pounds make one stone in British usage.
The stone (st) equals exactly 14 pounds (about 6.35 kg). It is still widely used in the United Kingdom and Ireland to state body weight, even though it is no longer legal for trade. The stone was originally a real stone used by merchants as a counterweight on balances; its weight varied by region and trade until standardized in the late 19th century.
