utility that I wrote back in 1998. It's a small (20KB), fast, self-enclosed, completely customizable
script file that can be downloaded and run locally. JSUC can convert between
several different units (approx. 250!) in a number of physical properties: it can convert
between Celsius and Fahrenheit, inches and meters, mph and kph and a lot of
other esoteric units you've probably never heard of.
Run JSUC Now!
How to use it
When you load up JSUC (by selecting the JS Unit Converter link on the top right of this page --go ahead and do it now), you'll get 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 (the most common US highway speed limit) to kph:
You should get something approximately equal to 120.709 kph (depending on the
accuracy of the machine you are using).
- 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
- 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.
Local Use and Reference Data
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.
You can do that by right-clicking (or holding down the mouse button for Macs) on
the JS Unit Converter link on any JSUC page 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.
The "Reference Data" link will supply you with
some handy constants and other frequently used numbers in a number of fields.
be done better. I just think it's a nifty thing to have around,
especially if you are an engineer or a scientist, stuck on an obscure unit and
all you've got is some high-end workstation where no-one bothered to write a
utility like this.
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!
If you're curious, JSUC is based on an earlier utility of mine,
Total Control Converter for Windows 3.1
