Sometimes good things come in not-very-fancy packages. That's definitely the case with Conversion Calculator. It's not much to look at, but it may well be the most comprehensive conversion calculator we've ever seen.
The program's interface is quite plain; it's not particularly attractive, but it is intuitive. There are spaces for your source value and the conversion, a number pad (with keys for entering negatives and fractions), and two absolutely huge dropdown menus that contain the various units that the program can convert. We encountered quite a few units we'd never even heard of, although we did notice that common cooking measurements were absent; if you need to know how many tablespoons are in a cup, this program can't help you. One thing we loved about Conversion Calculator was that it doesn't make users scroll through this monstrous dropdown to find the unit they're looking for; there's also a small letter keypad, and users can click on the first letter of their unit to skip to it automatically in the list. Conversion Calculator also lets users specify the maximum number of digits in a number as well as the number of decimal places. A built-in Help file provides a thorough overview of the program's features. Overall, we were quite impressed with Conversion Calculator, and we think it's a great thing to have around whether you're building something, doing your science homework, or working with any other units of measurement that need conversion.
Conversion Calculator comes as a ZIP file and doesn't require installation; at 913K, it's a great tool to keep on your USB drive.
