About MedMaths

What MedMaths is

MedMaths is a free set of clinical calculators and step-by-step medication math learning for nurses and healthcare students. Every calculator shows its working, so you can check the answer and see how it was reached.

Who checks it

George Lambroglou, a registered nurse, created MedMaths and checks the formulas, worked examples and safety text against their original sources. Each page shows when it was last reviewed. How we check our work.
