About the unit converter
Ten measurement families covering the conversions that come up day to day, with 90+ units in total. Pick a category, choose your units and the result updates as you type in either direction. A swap button flips the pair, and a reference table underneath shows the same value expressed in every other unit of that category at once.
This tool runs entirely in your browser. Nothing you type is uploaded, and it keeps working with no connection at all — including as an installed app.
