About

This site is about helping you make calculations using intelligent expression evaluation online applications. In making this website, I wish to improve your analysis accuracy and efficiency by providing you with accurate calculations for complicated expressions. The examples available at the following links will be periodically updated to include problems from all interests including science, chemistry, physics, engineering, finances and biology. See the Stress Analysis eBook for an example of this kind of website. Email me to include new problem solutions, perform calculations or develop engineeing solutions for your unique needs.


Expression Evaluator

The web application calculates expressions. Any expression can be evaluated. Unique functions that automatically handle units are also available. Enter your expression as a formula and it's input units as a "text formula" with the "CVVAL()" function. Then enter the desired output units. Any proper combination of units will be automatically evaluated. The expressions follow MS VBasic syntax. The application will calculate the expression value after defining the correct conversion factor(s) for the entered units. It will verify that the desired output units are proper. Any BASIC expression can be used - it does not need units - as if this was a statement calculator. A series of conversion functions is listed with examples.


Complex Unit Converter

This web application converts complex expressions with units properly handled. Enter the value expression and its unit string as formulas. Also enter the desired output unit expression string. The Complex Converter will calculate the value, define the conversion factors for the unit expressions and verify that the desired output unit expression is proper. Numerous examples from science, chemistry, engineering and other disciplines are available and will be added.
