About stone and micrograms
Stone (st)
The stone is a British unit equal to 14 avoirdupois pounds (6.35029318 kg). It is used mainly for body weight in the UK and Ireland.
Microgram (µg)
A microgram is one millionth of a gram (one billionth of a kilogram). It is used for very small doses such as vitamins, hormones and trace substances, often written mcg.
