About PsyCalc

Its intuitive interface, flexibility and wide operating range makes it the tool of choice for tens of thousands of professionals worldwide. The rigorous calculation engine driving PsyCalc® is recognized by many engineers as the gold standard.

PsyCalc® operates in I-P (inch-pound or English) units or SI (System International or metric) units. Input and output values can be set to different units providing an easy means to make conversions.

PsyCalc® is immediate. Make a change to the inputs and the outputs are updated immediately. There is no calculate button, all values are always up-to-date and valid.

Numeric inputs are entered via a numeric keypad.
