PCalc is the powerful choice for scientists, engineers, students, programmers, or indeed anybody looking for a feature rich calculator. It includes an optional RPN mode and multi-line display, a choice of button layouts, an extensive set of unit conversions and constants, a paper tape, multiple undo and redo, engineering and scientific notation, as well as support for hexadecimal, octal, and binary calculations.PCalc is ideal for scientists, engineers, students, programmers, or indeed anybody looking for a feature rich calculator.

What's New in Version 4.3
Added full support for OS X 10.11 El Capitan.
Added an option to float the PCalc window above all other apps.
Added the "Split Screen iPad" layouts from PCalc on iOS 9.
Added a delta percentage button to most layouts as the 2nd function of percentage.
You can now paste simple calculations into PCalc.
Changed behaviour of the percentage key in algebraic mode to match the Apple calculator - old behaviour still available via "Display percentage result" option in Advanced section of Preferences.
Now display "Error" rather than just blinking the display on an incorrect operation.
Fixed a problem editing user functions and conversions with conditional skip commands.
Core code has been updated to match PCalc 3.5 on iOS.
Best Mac Calculater Ever (Literally)!
Been a PCalc user from the old Macintosh SE days. It was the best straight-up calculator for the Mac back then, and still is now.
Yes, the “natural language” calculators are powerful and better suited for more narrative mathematical tasks, but more often than not, I just need to crunch numbers. PCalc lets me do that simply, attractively, and in my preferred way.
Worth every penny!
Best in Class
I am not a frequent calculator user but when I need one, I need power. This has been my mainstay for I think well over a decade.
When Siri or Google isn’t enough, this is the one
Easy to get started and use for simple tasks, yet powerful enough for more advanced problems. Choose your display: normal, scientific, engineering, or accounting. Don’t like algebraic entry? Okay, they’ve got RPN for you, as well. Has a tape feature, so you can check the accuracy of your entries. No more adding a column of numbers multiple times, trying to get a consistent result. About the only notable thing I haven’t found yet is a graphing function, but that may just be me. This program is pretty deep, while still having a “shallow end” for newbies. Need conversions? PCalc has them for 19 categories of measurement: angle, area, bytes, cooking, currency, density, energy, force, fuel efficiency, length, lighting, power, pressure, speed, temperature, time, torque, volume, and weight. I threw away my separate units conversion program; it was harder to use and handled fewer conversions. Need built-in constants? They’re available in seven categories: astronomical, atomic, electromagnetic, mathematical, physiochemical, universal, and user-defined. Built-in functions in six categories, including user-defined. Also, PCalc has a corresponding iOS version, so you can have it on your desktop and on the go. I already thought it was just about perfect, but TLA Systems (the authors) seem to keep finding ways of making more improvements. Highly configurable. Highly accurate. Highly recommended. Sorry to gush, but I just think it’s that good.
