mcg/kg/min to mL/hr Converter
Weight-based infusion math done in seconds. Enter dose in mcg/kg/min, patient weight, and drug concentration — get a pump-ready mL/hr value.
The formula
mL/hr = (mcg/kg/min × kg × 60) ÷ mcg/mL
The ×60 converts minutes to hours. Concentration (mcg/mL) is derived from the amount of drug dissolved in the total bag volume — e.g., 4 mg dopamine in 250 mL = 16 mcg/mL.
Common mistakes
- Forgetting to convert mg to mcg before dividing (×1000).
- Using total drug amount instead of concentration per mL.
- Not updating weight when patient weight changes post-admission.
Frequently asked questions
Why does the formula multiply by 60?
Pump rates are in mL/hr but the dose is ordered per minute. Multiplying by 60 min/hr converts the dose to a per-hour value before dividing by concentration.
What if my drug is ordered in mcg/min, not mcg/kg/min?
Select the "mcg/min" unit mode. The formula then drops the weight term: mL/hr = (mcg/min × 60) ÷ mcg/mL.
How do I handle titrations?
Simply update the dose field — the mL/hr result updates instantly. No recalculating needed during titration events.
