Calculate weight-based medication doses in mg and mL. Enter patient weight, dose per kg, and concentration for pediatric and adult nursing dose calculations.
Calculate albumin-corrected serum calcium for hypocalcemia assessment. Enter total calcium and albumin to get corrected calcium level in mg/dL.
Calculate pediatric BMI and BMI percentile by age and sex. Uses CDC growth chart data for children ages 2–19 weight status screening.
Basic flow rate before converting to drops. Pump IVs display mL/hr directly.
mL/hr = Total Volume (mL) ÷ Time (hours)Drop factor depends on tubing: macrodrip 10, 15, or 20 gtt/mL; microdrip 60 gtt/mL (1 gtt = 1 mL).
gtt/min = (Volume × Drop Factor) ÷ Time (minutes)Rearrange to verify infusion completes within ordered timeframe.
Time (min) = (Volume × Drop Factor) ÷ gtt/minUpdated: July 2026
125 mL/hr = 31.25 gtt/min (round to 31 gtt/min). Verify drip count for 1 full minute.
Pump rate 1,000 mL/hr. Gravity with 20 gtt/mL: 500×20÷30 = 333 gtt/min — use pump for short infusions.
60 gtt/mL set: 100×60÷240 = 25 gtt/min. Microdrip where 60 gtt ≈ 1 mL simplifies pediatric math.
Calculate gravity IV infusion rates for nursing clinical practice and exams. Enter total volume, infusion time, and drop factor (10, 15, or 20 gtt/mL) to get drip rate in drops per minute and mL per hour.
