2@DoritoStyle Software recommendations are on-topic here. This is however a very bad one that should not have amassed such a large number of upvotes but rather closed as unclear - it lacks every information necessary to answer.– pipeSep 26, 2018 at 23:23

3On the basis of my previous comment I've flagged this for closure until OPs definition of "good" is added, otherwise it will just be a list of every calculator software. Maybe fine 10 years ago, but not these days.– pipeSep 26, 2018 at 23:25

3@pipe My way of interpreting "good" is "useful" according to two criteria. 1. It works like a calculator works, not like an IDE. 2. It works in an intuitive way that doesn't require any knowledge of programming. That's a reasonable definition of good for a question like this, not very fuzzy in the context of a question about a graphical calculator application, and I also don't like setting impossible standards of refinement for formulating questions or else we could close almost anything.– karelSep 28, 2018 at 12:36

Most famous ones are:
- Gnome Calculator
- galculator
- xcalc
- kcalc
They all have basic and scientific modes.
By default Ubuntu comes with "Gnome calculator" unless you are using a specific flavor of Ubuntu.
Gnome Calculator:
For example in "Kubuntu" you should have "kcalc".
Kcalc:
galculator
There are other options available too like "xcalc", I use galculator
myself, install it using:
sudo apt install galculator
It's lightweight and really fast, doesn't have much dependencies, easy to use and has nice features.
Paper Mode:
Scientific view:
Extcalc
If you are looking for something with more features then I guess you are looking for "Extcalc".

1I like galculator a lot -- it came default with 16.04 MATE, and toggles between algebraic and RPN as well as turning on-off scientific functions and some other stuff I never use. I may have to give extcalc a try, too. Sep 26, 2018 at 13:49

I like
kcalc
a lot because all I need is a simple adding machine. Now, if it only had a "tape"/history feature! The only calculators I found that have it are way too complicated for my needs.– JoeSep 27, 2018 at 7:07 -
The name galculator is not convenient for user experience because after installing it, we cannot find the app if we start typing calc (for calculator) in the apps search of the desktop environment.– baptxMar 14 at 16:10
If your calculations involve units, such as with physics or electronics equations, I would recommend Qalculate.
It supports using units in expressions, so you do not have to worry about unit conversions manually. It is also a good check for whether you have typed the correct equation (this is called Dimensional analysis).

Pretty cool handling of units indeed, eg 19h32min−16h45min = 2 h + 47 min Mar 10, 2022 at 18:30
I am personally a fan of speedcrunch, because it has a decent list of common physical and chemical constants and remembers your history across sessions:
As noted in the comments by @Michael:
[It is also] easy to mix/convert hex, bin and decimal representations of numbers. With mask() and unmask() it’s also possible to reduce/extend numbers to certain bit widths.

3As a digital design engineer I also love it because it’s so easy to mix/convert hex, bin and decimal representations of numbers. With mask() and unmask() it’s also possible to reduce/extend numbers to certain bit widths.– MichaelSep 27, 2018 at 9:18

@Michael I have never used it for this, but this sounds like I might in the future, instead of doing it in Python.– GraipherSep 27, 2018 at 9:20

Does anyone know how I can convert a result like 1333333333,33333 in scientific form quickly with Speedcrunch?– AndycFeb 9, 2021 at 21:32

I am using it everyday as well, but I just saw it might be heavy.
