About the Converter
There are three drop down menus: 1) a menu labeled "Property," 2) one labeled "A," and, 3) another labeled "B." The "Property" menu lists all the different properties written in JSUC; it defaults to the first one, usually "Acceleration," but you can select anyone you wish by dropping down the menu. When you select a property, the options in the "A" and "B" menus are automatically updated to the supported units of the selected property.
Say you want to convert 75 mph to kph:
Select "Velocity & Speed" from the "Property" menu: Both "A" and "B" menus default to 'Meter/Second (m/sec)."
Select 'Mile (US)/hour (mph)' in menu "A" (you could use B, it doesnt really matter).
Select "Kilometer/hour (kph)" in menu "B".
Plug "75" (no quotes) in the input box next to menu "A".
Hit the button "Convert to B" which is next to the box you entered "75" in.
You should get something approximately equal to 120.709 kph (depending on the accuracy of the machine you are using). Now, if you are a European, you can go ahead and laugh...

JSUC is written to be self-enclosed and autonomous: you can download it to your hard disk or UNIX account and use it from your own browser, without putting too much strain on the already overworked Nyx. You can do that by right-clicking (or holding down the mouse button for Macs) on the Current JSUC link and select"Save Link As..." or something else to that effect. Then, by using the File menu command for opening a local file (depending on your browser) you can run your local copy. Since the JSUC file is only about 20k it should be blazingly fast on most systems. The "Current JSUC" link provides you with a live link to my copy of JSUC, so you can re-download it for any updates or changes.
Because JSUC is essentially a big script, all the source code is there for anyone to see; you are free to do what you want with it: change it, deface it, customize it, add to it. If you do, please read the comments in the actual file to guide you and give me a credit somewhere.
