What these converters tools cover

The largest group on the site: everyday measurement swaps and format changes. Pressure pairs such as bar to psi and atm to kPa, length, weight, temperature, area, volume, speed and data sizes, plus number bases and case conversion. Each converter uses the standard definition — for example 1 bar equals 100 kPa exactly — and shows the working so you can check it rather than trust it.

Common jobs

Checking tyre pressure or compressor ratings in the unit your gauge uses
Converting a recipe between cups, millilitres and ounces
Turning a CSV column into the unit a client asked for

Why they run on your device

These pages are static files. The work is done by JavaScript in your tab, so a file or a password never leaves your machine — there is no upload endpoint on this site to send it to. That also means no account, no usage counter and no queue.

Questions

Are the conversion factors exact?

Most are exact by definition, such as 1 bar = 100 kPa or 1 inch = 25.4 mm. A few are rounded conventions and the page states the factor it used.

Why so many single-pair pages?

A page that answers exactly one question — bar to psi — is faster to use and easier to check than a form you have to fill in.
