Dosage calculators
14 calculators that show every step, so you learn the method instead of copying a number. Each one comes with the formula, worked examples and practice problems.
- IV Flow Rate Calculator (mL/hr)Calculate the pump rate in mL/hr from the volume and the infusion time, with every step shown the way nursing programs teach it.
- IV Drip Rate Calculator (gtt/min)Calculate drops per minute for a gravity IV infusion from the volume, the time and the drop factor of the tubing, with each step explained.
- IV Infusion Time CalculatorFind how long an IV will take to infuse, and the time it will finish, from the volume and the rate in mL/hr.
- Tablet Dosage Calculator (Desired over Have)Calculate how many tablets or capsules to give with the desired over have formula, including g, mg and mcg conversions.
- Liquid Medication and Injection Dosage Calculator (mL)Calculate how many mL to give for oral liquids and injections with desired over have × quantity, and the right rounding for the syringe.
- Weight-Based Dosage Calculator (mg/kg)Calculate doses ordered in mg/kg, mcg/kg or units/kg, per dose or per day divided, with pounds to kilograms conversion and the volume to give.
- Pediatric Safe Dose Range CalculatorCheck whether a pediatric order is within the safe dose range in mg/kg/day or mg/kg/dose, the way you are asked to on nursing exams.
- mcg/kg/min to mL/hr Calculator (IV Drips)Convert a weight-based critical care infusion in mcg/kg/min, or a dose in mcg/min, to a pump rate in mL/hr, and back.
- Heparin Drip Calculator (units/hr to mL/hr)Calculate a heparin infusion rate in mL/hr from units/hr or a weight-based order in units/kg/hr, and the bolus dose in units.
- Insulin Drip Calculator (units/hr to mL/hr)Calculate the pump rate for an IV regular insulin infusion from units/hr or units/kg/hr, or find the units/hr infusing from the rate.
- Reconstitution Calculator for Powdered MedicationsCalculate the mL to withdraw after reconstituting a powdered medication, using the concentration printed on the label, and how many doses the vial holds.
- Body Surface Area (BSA) Calculator and mg/m² DosingCalculate body surface area with the Mosteller formula and a dose ordered in mg/m², from height and weight in metric or US units.
- Nursing Unit Conversion CalculatorConvert the units used in medication math and patient care: g, mg and mcg; L and mL; pounds and kilograms; teaspoons, tablespoons and ounces; inches and cm; °F and °C.
- Percent and Ratio Solution Calculator (mg/mL)Convert solution strengths given as a percent (2% lidocaine, D5W, 50% magnesium sulfate) or a ratio (1:1,000) to mg/mL, and find how much drug is in a volume.
