Looking for a conversion chart?  Here you can make online conversions (e.g. metric conversions) for many measurement systems.  There are conversion tables for both common (U.S., metric, etc.) and quite exotic units like Ancient Greek and Roman.  You can also ask questions and discuss how to convert units on the Units Conversion Forum.

Calculator Tab is a free online scientific calculator which works like your regular calculator. One feature that sets it appart from other calculators is that it's memory bank can store an unlimited amount of numbers and descriptions of these numbers for an indefinite length of time. The stored numbers can be sorted by date, by the number of uses or by name. Your saved numbers and their respective descriptions are saved directly on your computer, never entering the sphere of the internet, so that they are as secure as your workstation.
