Does convert-me.com really exist since 1996? In fact it's even older. We launched the first version of our online units converter in 1995. There was no JavaScript there and all conversions had to be done on server. The service was slow. A year later the technology allowed us to create an instant units conversion service that became the prototype of what you see now.
To conserve space on the page some units block may display collapsed. Tap any unit block header to expand/collapse it.
Does the page look too crowded with so many units? You can hide the blocks you don't need by clicking on the block headline. Try it. Clicking again will expand the block.
Our goal is to make units conversion as easy as possible. Got ideas how to make it better? Let us know
