Formulas & rounding
The formulas, made visible.
mcg = mg × 1,000; mg = mcg ÷ 1,000
Decimal inputs use integer-ratio arithmetic. Display values round to six decimal places (four for syringe markings; nine for mass conversion). Rounding does not establish measurement accuracy.
Arithmetic only. Dose, stability, sterility and compatibility are not assessed. Research vials are not intended for personal use.
