The weight in pounds.

Most jobs need more than one number. Add the calculators you need next and they open right here, underneath this one — your figures stay on screen and nothing is lost to a page change.
Going from pounds to stone is mostly a translation job rather than an engineering one — a US figure being put into the unit a British reader thinks in. What makes it worth a page of its own is the remainder. Fourteen does not divide anything neatly, so a decimal answer of 12.5 stone is correct and unreadable, while the form people actually use is twelve stone seven. Both are given here, and the distinction matters more than it looks: the decimal is the one to carry into any further calculation, and the whole-stone-and-pounds line is the one to say out loud. Where a limit is involved rather than a conversation, keep the comparison in kilograms and let the stone figure stay a courtesy.
