About Microgram and Stone
The microgram is one millionth of a gram. It appears on supplement labels (often as mcg or µg) for vitamins like B12 and D, and in toxicology and air-quality limits. The stone equals 14 pounds, exactly 6.35029318 kilograms. It survives almost exclusively for stating body weight in the UK and Ireland. One Microgram equals 1.574730e-10 Stone (1 ug = 1.574730e-10 st). Microgram to Stone conversion comes up most often in vitamin labels (mcg) and in air quality limits, typically when figures need restating for body weight in the UK and Ireland.
Precision and Rounding: Metric-imperial mass factors are exact (1 lb = 0.45359237 kg by the 1959 agreement), so precision is purely a display choice. One decimal place is enough for body weight and cooking; nutrition labeling, pharmacy, and lab work need the full factor before rounding.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
