Flip a dose between mcg, mg and IU without second-guessing a decimal — plus a per-kilo helper for bodyweight-based doses.
Type a value, pick its unit — Carl shows all three.
IU (international units) aren’t a fixed weight — the conversion is defined per substance by its potency. The factor above only applies to the IU column; mcg↔mg is always ×1000.
For protocols written as “X mcg per kg.”
Total = dose-per-kg × bodyweight. Bodyweight-based dosing is common in animal research; human research-use figures are usually fixed amounts.
