Drug Dosage & IV Infusion Rate Calculator
Precise clinical computational engine for IV flow rates ($gtt/\min$), weight-based pediatric/adult dosage ($mg/kg$), and vial reconstitution.
Infusion Parameters
Enter total IV volume, administration duration, and tubing drop factor.
Calculated Infusion Rates
42 gtt/min
≈ 1 drop every 1.4 seconds (0.70 drops/sec)
Volumetric Rate
125.0 mL/hr
Total Duration
240 mins
Working Formula:
Rate = (Volume × Drop Factor) ÷ Time (min)
= (500 × 20) ÷ 240 = 42 gtt/min
Clinical Reference & Standard Drip Factors
Macrodrip Tubing (Adults)
Standard macro sets deliver 10, 15, or 20 drops per mL. Used for general intravenous fluid infusions (Normal Saline, Ringer's Lactate, Dextrose) in adult wards and surgical units.Microdrip Tubing / Soluset (Pediatrics)
Microdrip sets deliver exactly 60 drops per mL (1 mL = 60 gtt). Consequently, the drop rate in gtt/min is numerically identical to the flow rate in mL/hr.
