About EMT Calculator Tools

A hobby project to help Emergency Medical Technicians and students

Project Background

EMT Calculator Tools is a personal hobby project created by Austin Cole, an EMT student in Idaho. This collection of calculators and reference tools was born from a simple need: having easy access to essential medical calculations during EMT OM (Optional Modules) class and in the field.

The project started as a way to digitize calculations that EMTs, AEMTs, and Paramedics use regularly, making them easily accessible on any device, even offline. Each tool is designed with real-world EMS scenarios in mind, following manufacturer guidelines and established medical formulas.
