Below is a list of math based calculators, conversion charts and converter programs available for use. Some of these are directly related to interest in math and some are of indirect interest; often they are of interest in our day to day lives, be it for calculating a car's fuel efficiency, or predicting the outcome of an election. We have written these or provided these for actual use and convenience, rather than for strictly educational purposes, though homework is a frequent and valid use. Each program applet in this particular group has a highly functional purpose. Each menu item has a descriptive pop-up that will appear, giving detailed information of that selection, as the mouse is rolled over the menu item. We are always receptive to comments or suggestions you may have. We also have a list of pure educational math converters and calculators, designed for educational reasons; source code is free for your use on those. Enjoy!
