Medication maths for clinical practice
Medication dose calculators for nurses and clinicians.
Use focused calculators for mg to mL conversions, tablet dosage, IV drip rates, infusion time, dilutions, BSA, ideal body weight, and Cockcroft-Gault creatinine clearance.
Most useful medication maths tools
Focused calculators for dose conversions, tablet dosing, IV rates, dilutions, and dosing weight checks.
mg to mL Calculator
Convert medicine dose in mg to volume in mL using concentration.
Tablet Dosage Calculator
Work out how many tablets are needed from dose and strength.
mL/hr to gtt/min
Convert IV pump rate to drops per minute using drop factor.
gtt/min to mL/hr
Convert manual drip count back to an hourly IV rate.
Infusion Time Calculator
Calculate how long an IV infusion will take or has remaining.
C1V1 = C2V2 Calculator
Calculate dilution volume from stock and target concentration.
BSA Calculator
Body surface area calculation for dose checking and clinical notes.
Creatinine Clearance
Cockcroft-Gault CrCl estimate for renal dosing context.
Browse the focused calculator set
Each calculator is built around one search intent, one formula, clear units, worked examples, and safer medication maths scope.
Dose Calculations
mg to mL, mg/kg to mL, and units to mL dose checks.
Tablet & Oral Dosing
mg to tablets and weight-based tablet calculations.
IV Fluids & Infusions
mL/hr, gtt/min, and infusion time calculations.
Dilutions & Reconstitution
C1V1=C2V2, vial dose to mL, and reconstitution calculations.
Dosing Body Measures
BSA and ideal body weight for medication dose context.
Renal Dosing Support
Creatinine clearance for medication dosing context.
Why this focused library is stronger
MedMaths is built around the medication calculations people commonly need to check: dose conversions, tablets, IV rates, dilutions, body measures, and renal dosing support.
Calculation first
Pages put the calculator, formula, and worked examples before long educational content.
Nursing-friendly wording
Labels use real medication maths language, such as mg/mL, mg per 5 mL, tablets, gtt/min, and mL/hr.
Safer scope
The site stays in a narrow lane: medication maths, not broad diagnostic scoring or general medical calculators.
