About the stone and the ounce

The stone

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.

The ounce

The avoirdupois ounce (oz) is a unit of mass in the imperial and US customary systems, defined as exactly 28.349523125 grams (1/16 of an avoirdupois pound). It is the standard small-mass unit in the United States for food packaging, recipes, and postal weights. Do not confuse it with the troy ounce (used for precious metals, 31.1035 g) or the fluid ounce (a volume).
