sometime back I saw a calculator with currency conversion built-in with an option to update to current rates if so desired. Does anybody know what I'm talking about ? Saw it in debian.



Install the qalculate-gtk package:

Qalculate! is small and simple to use but with much power and versatility underneath. Features include customizable functions, units, arbitrary precision, plotting, and a graphical interface that uses a one-line fault-tolerant expression entry (although it supports optional traditional buttons).

apt install qalculate-gtk

start the application , you will see the following message:

You need to download exchange rates to be able to convert 
between different currencies. You can later get current 
exchange rates by selecting "Update Exchange Rates" under the File menu.

Do you want to fetch exchange rates now from the Internet?

Hit Yes , from the menu select Units then currency .


apt install gnome-calculator


The GNOME calculator is a powerful graphical calculator with financial, logical and scientific modes. It uses a multiple precision package to do its arithmetic to give a high degree of accuracy.

From the Advanced Mode choose Financial Mode. Also the keyboard mode allow you to convert currency.

  • actually this is the package I was looking for, unfortunately in debian the package is far too old, the newest version has the thing I want the most. Huge improvements in the basket of currencies. – shirish Dec 12 '17 at 5:00
  • @shirish Please see my update. – GAD3R Dec 12 '17 at 9:05
  • I saw that, alas it seems you have to get the rates manually in, there is no way for it to get rates from central bank or money exchange markets and give you current rates which is what the newer and newest versions of qalculate-gtk do (along with more currencies added to it ) – shirish Dec 14 '17 at 7:12

1) Keurocalc?

KEurocalc is a universal currency converter and calculator. It downloads latest exchange rates directly from the European Central Bank and Time Genie.

2) Or you can just use Chromium browser. e.g. Input into the address bar

convert 500 usd to gbp

  • The only problem with kerocalc is that it takes Euro as the default currency, I wish there was a way to change that but seems there isn't. – shirish Dec 12 '17 at 4:59

From the command line:

# from Ambrevar https://bbs.archlinux.org/viewtopic.php?pid=1568235#p1568235

if [ $# -ne 3 ] || [ "$1" = "-h" ]; then
    cat <<EOF

CURRENCY is a 3-letters code like EUR, SEK, USD, etc.

curl -sA "Mozilla/5.0" "https://finance.google.com/finance/converter?a=$1&from=$2&to=$3" | \
    awk -F '<|>' '/result/ {print substr($5,1,length($5)-6)}'
  • No longer works: your computer or network may be sending automated queries even though I only tried once – user640916 Jul 29 at 19:43
