Unit Converter
Convert measurements
Unit Converter: Convert measurements. A free, browser-based tool from DevToolbox that runs entirely on your own device: no upload, no account, no tracking.
About the Unit Converter
Free online unit converter. Convert between common units of measurement including length, weight, temperature, and more. It is one of the utilities tools on DevToolbox, and like all of them it runs entirely in your browser.
The calculation is done with the same maths a browser or design tool uses internally, so the values match what you will see when you paste them into CSS, a terminal or an editor.
What you can do with it
- Measurement converter
- Length converter
- Weight converter
- Temperature converter
How to use it
- Enter your value in the input.
- The equivalent forms are calculated immediately.
- Adjust any options to change the output format.
- Copy the value you want.
Questions
- Is my data uploaded anywhere?
- No. The tool is JavaScript that runs in the tab you already have open, and DevToolbox has no backend to send anything to. You can open the network tab and watch: after the page and its script load, nothing is sent while you work.
- Does it work offline?
- Once the page has loaded, yes. The tool needs no network access to do its job, so it keeps working if your connection drops. Reloading the page does need the network unless your browser has it cached.
- Is it free, and do I need an account?
- It is free and there is no account, no sign-in and no usage limit. There is nothing to register because there is no server keeping track of anything.
