About Unit Converter
Unit Converter handles conversions across length, mass, temperature, area, volume, speed, data, and time in one place. Reach for it when a recipe is in grams, a spec sheet is in inches, or a download is quoted in mebibytes and you need the figure you actually use. It runs in your browser with no uploads and no server call.

Frequently asked questions
Which categories of units are supported?
Length, mass, temperature, area, volume, speed, data, and time, each with both metric and imperial units where applicable.
Do I need to upload anything?
No. You enter the value and pick the units; the tool generates its own input and converts locally in your browser.
Is my input private?
Yes. The conversion runs entirely on your device, so nothing you type is sent to a server.
How is the result returned?
As JSON, so the converted value is easy to read and to feed into other tools or scripts.
Does it convert currency?
No. Currency needs live exchange rates, which this offline tool doesn't fetch. It covers physical and digital measurement units only.
