Easy calculation of scaling percentages & unit conversions
Not all of us remember the days of proportion wheels, those plastic devices now stuck in a drawer somewhere, yellowed and cracked. And they were never completely accurate or easy to use. Times have changed.

DesignSoft's ProWheel and ProWheel Plus bring easy, accurate calculation of percentages of enlargement and reduction right on your screen. ProWheel pops-up (not an extension though) anytime you need it for on-the-spot figuring. Enter decimals, fractions, or a combination—doesn't matter. Convert any unit of measurement to another with a click on the pull-down menu—from picas to millimeters to inches.
