When measurements cannot be recognized, the functions return a string error message suggesting possible alternatives which either sound alike or partially match the unknown name. Additional user-defined definitions can be easily embedded within the source code itself. Also contains functions for reading conversion factors from a text file. Conversion factors are read from text files in the form of Basic function calls. This single format for specifying unit and prefix definitions means that they can be freely moved between the source code, external text files, and the user-defined definitions box in the Windows executable program.
Functions cache certain important operations to improve the performance of subsequent calls.
Conversion functions can determine if cycles exist within the unit and prefix definitions. This means that developers can use the Standard Edition of Visual Basic to modify, run, and compile the software. API Overview estConvert performs measurement conversions given a numeric measurement, the units of that measurement, and the desired units for the result. Miscellaneous Built-in definitions include several physical constants. Supports the conversion of temperatures which have different base scales.
