Stones (st) to Milligrams (mg) Conversion
Stones
The stone is a unit of mass equal to exactly 14 pounds (approximately 6.35 kilograms), used almost exclusively in the United Kingdom and Ireland for expressing human body weight. Standardised by the Weights and Measures Act of 1835, the stone persists in British popular culture and medical contexts despite not being part of the SI system.
Milligrams
The milligram is a unit of mass equal to one thousandth of a gram (10⁻⁶ kg) and is the standard unit of dosage in pharmacology and clinical medicine. Drug doses, vitamin quantities, and mineral recommended daily allowances are routinely expressed in milligrams, where precision is critical: in many medications the therapeutic margin is narrow, making accurate measurement a matter of patient safety.
