What is WhatMaths

WhatMaths is a collection of free online calculators and math tools. It includes a scientific calculator with a step-by-step equation solver, a percentage calculator, a fraction calculator, temperature and length converters, a loan calculator, and formula reference sheets for algebra and the GED. Everything runs directly in your browser, so results appear instantly and nothing needs to be installed.

Our goal

We want everyday and school math to be simple. That means clear layouts, quick answers, and worked steps where they help you understand how an answer was reached.

Free and private

All tools are free to use, with no account and no sign-up. Your calculations are processed in your browser and are not sent to our servers. You can read more in our Privacy Policy.

Accuracy

Our tools are built on standard mathematical formulas and are tested before release. Even so, please verify important results independently. See our Disclaimer for details.
