Microsoft Calculator Plus
Microsoft released this simple “Calcuator Plus” which has a basic interface that looks just like your normal calc.exe in standard or scientific mode, and then … it has a conversion mode which can convert pretty much anything. How about “Miles Per Gallon(US)” to “Kilometers per Liter”? Easy you say … Google can do that! Well, how about Belgian Franc’s to Greek Drachmas? That’s right, it even does currency conversion, curtesy of rates downloaded from the European Central Bank (although, I found the list curiously lacking). Anyway, it’s interesting, and … skinnable? (Well, it has one skin, anyway), and you can get it from here" and try it, especially if you have need of converting from obscure units of weigh like the “chung,” “harb,” or “saloung”, into nice useful units like pounds, grams and carats.

Side note: if you need a graphing calculator, or a calculator with a “tape,” there’s one in the Powertoys from Microsoft.
