Why Tooligan

Tooligan is a small, independent project building fast, single-purpose tools for the everyday calculations and conversions that shouldn't need an account, a download, or an app. Open a page, get your answer, move on.

We add tools steadily and only publish a calculator once we've checked its output against worked examples. Every tool comes with how-to steps, examples, and answers to common questions — so you understand the result, not just the number.
