PhySyCalc for Mac1.20

Great little app! I use it not only for calculations involving units but also for unit conversions (quicker and easier than most of the convoluted unit converter out there).

A very helpful calculator! Small and very fast. And works with every macOS! A big thanks to the developers...

Wow! Where do I start? This app is a complete game changer as a scientific calculator. I’ve never seen a calculator app that lets you add, subtract, multiply, divide all your numbers with units and then lets you select the answer in whatever unit you desired. It's a paradigm shift. Normally I do the calculation twice, first in a calculator using only the raw numbers without any units, and then on paper, checking that the units all cancel and you get the correct answer in the correct unit. With this app I can do it all in one step. And getting the answer in the desired unit is a simple matter of scrolling through the list of possible answers to find the one in your desired unit. Where was this app when I was doing all my chemistry homework problems? Another cool feature is that it has buttons for all the important physical constants with units, so no need to look those up. You can even recall atomic weights using only the element symbol.
