IV Fluids and Infusion Calculators
Focused IV maths tools for converting mL/hr, drops per minute, and infusion time.
mL/hr to gtt/min Calculator
Convert an IV pump rate into manual drops per minute using drop factor.
gtt/min to mL/hr Calculator
Convert a manual drip count back into an hourly IV rate.
Infusion Time Calculator
Calculate time to finish from remaining volume and mL/hr rate.
How IV fluid calculations work
IV calculations usually connect three variables: volume, time, and rate. Pump calculations use mL/hr. Gravity calculations use drops per minute and the giving set drop factor.
The most common safety issue is using the wrong drop factor. Always check the giving set, pump order, fluid order, and local policy before making changes.
Safety note: IV rate changes can be clinically significant. These calculators support arithmetic checking only.
