9 Awesome Calculator and Converter Apps for Mac

Your Mac already comes loaded with three functional calculators: the actual application “Calculator”, the Dashboard calculator and the Spotlight calculator. However, all three of these lack certain advanced functionality that you may need.

Calculator Apps

PCalc

PCalc 3

PCalc has been around for a very long time, and now it even has an iOS app. Think of it as a more professional, jacked up version of the calculator that came with your Mac.

Some of the extra features include support for Hexadecimal, Octal, RPN and Binary modes, conversions, a log of all your operations that you can save, styles, and even an included simpler Widget version of PCalc for your Dashboard.

Calcline

Calcline

Calcline’s layout is close in resemblance to Soulver’s, though not quite as well polished. It has a variable system where you can set values for variables to use in your operations. It also doesn’t have a keyboard layout, and you have to type your operations in a text box where a pull-down log below will break them down into steps for you.

It also has some pull-down menus where you can choose functions that are hard to perform with your keyboard, like square roots and trigonometric functions. It’s definitely a solid, cheaper alternative to Soulver.

Soulver

Soulver

While the most expensive option, Soulver is definitely one of the most solid alternatives in this field. Not only is the interface simple and pretty, it’s also very functional. It doesn’t have a keyboard layout, instead you type your operations into one of the columns and your result will be displayed in the next column.

This way you can have different operations divided into lines so that you can use the older ones later. It has support for variables, currencies and stocks, while also adding some useful features like displaying your answers in a “big mode”, or degrees, hexadecimal and binary.

Mini Scientific Calculator

Mini Scientific Calculator

This is a much smaller, cheaper, simpler and less complete version of Advanced Scientific Calculator. It actually looks a lot like the Dashboard Calculator that comes with your Mac, but it has some more buttons and features that make it a scientific calculator. It lacks some features like a unit converter and a log, but for its price, it does plenty.

Price: $5
Requires: Mac OS X 10.4 or later
Developer: BlastOff Software

Advanced Scientific Calculator

Advanced Scientific Calculator

This app works in your Dashboard, but don’t panic, it’s actually very complete for a widget (and also very big). It has almost all the functions that your Mac Calculator does, and it also adds a log of your operations, RPN support and styles.

It even doubles as a very complete unit converter! It’s expensive, but if you’re looking for a widget calculator, this is the most complete one.

Price: $14.95
Requires: Mac OS X 10.4 or later

Currency and Unit Converters

iConvert

iConvert

iConvert is a free widget that allows you to convert pretty much any unit you could think of. It works through a system of categories – you choose one first (length, temperature, volume, etc.) and then it’ll display two textboxes with the units available (milimeters, grams, seconds, etc.). You type one in and it’ll update the other automatically. Simple and fast.

Price: Free
Requires: Mac OS X 10.4 or later

qwikCONVERT

qwikCONVERT

qwikCONVERT does what its name says: convert quickly. It works a little differently to the other converters, and I like it. It is also a widget, but instead of giving you two textboxes where you choose the units, here you only need to type the number and the unit (4 mm, 5 gr) and it’ll give you a list of conversions to the most popular units.

You can’t really choose the currency it displays things in, so if you are looking for some obscure unit most likely it won’t display it for you.

Price: Free
Requires: Mac OS X 10.4 or later

Unit Converter Pro

Unit Converter Pro

Unit Converter Pro is a bit of an unconventional widget (for me, at least). It works like most unit converters, but instead of having just two textboxes where you choose your units, you have to choose a category first and then it’ll display about a dozen textboxes with most units available for that category.

It’s definitely a different take on unit converters, and it has plenty of categories so I guess it could be useful for some people.

Currency Converter

Currency Converter

Currency Converter is a little Dashboard widget that makes this task very fast and simple. It sports four little text boxes where you can choose the currencies you’d like the widget to display. When you write inside a textbox it automatically updates the others with the corresponding data.

It has a very wide selection of currencies and it makes it very easy to update the exchange rates. It supports styles and has a useful set of options.
