PhySyCalc is the next generation scientific and engineering calculator with units—it makes the others seem like slide rules.

How is PhySyCalc different from other calculators? It allows you to include unit symbols in your calculations, obtaining the answer in the desired unit without those extra unit conversion steps. On top of this great simplification, PhySyCalc knows every fundamental physical constant. It even knows physical properties for elements and isotopes in the periodic table and can calculate formula weights. This allows you to get numerical answers in the desired unit in a fraction of the time you'd spend on a conventional calculator. PhySyCalc is quick to learn and easy to use. Can't remember a unit symbol? PhySyCalc helps you find and append commonly used units onto a number. PhySyCalc uses a natural infix notation for calculations. This means you can enter and read through the entire expression in full before calculating the result, helping you quickly identify and fix any input errors.

Not only does PhySyCalc save you time, it also saves you from mistakes. A conventional calculator will also give you a numerical answer, even if you accidentally multiplied instead of dividing. With PhySyCalc you’ll know right away that you entered the calculation wrong because the result will have the wrong units.

As a teaching tool PhySyCalc offers students better insights in the concepts of physical quantity, dimensionality, and units. A student using PhySyCalc soon understands the connections between the base SI quantities and all the derived quantities.

PhySyCalc's sole ambition is to be the world's best scientific "pocket" calculator.
