Free online calculators - such as an Ohms Law calculator or free online Financial calculator

Here are a few handy free online calculators. They are free for your use if you agree with terms on our website disclaimer, and agree to use it at your own discretion and risk. Right click on the program and save it to your hard drive.

I've made them so they will fit on mobile phones. I've used them on the skinny window of a Nokia 6300. You can transfer the program to your mobile if it can run FLASH SWF files. Small programs sitting on your phone which you carry with you all the time, just in case you forgot the formula to calculate a result while you are on site. Please read our website disclaimer before downloading and using these programs. Your browser should have the FLASH plugin to see these programs, and your security settings in the browser may have to be tweaked to allow FLASH to run.

The calculator will open in a new window when you click on the link.

You can download them by right-clicking on the links below and follow the browser menu that pops up for downloads. Either "Save link as..." or something similar.
