units - Unit-Aware Calculator

units is front-end for the powerful calculator and conversion tool GNU Units.

units

It supports a wide range of units - from physics to currency.

When converting, it offers only compatible units to convert to.

Installation

Install dependencies listed by this command:

 _common/assert_environment.sh units/units.sh

[if using Sxmo] Activate the tool by linking it into userscripts:

 ln -s ~/sxmo-onfire/units/units.sh ~/.config/sxmo/userscripts/

Run ./units.sh and enter the equation you intend to compute.

If you provide arguments, the tool will run non- or semi-interactively:

Solving an equation by providing it as the first argument:
```
  # non-interactive computation
  ./units.sh '6*7'
```

Providing a unit with the first and another as second argument:

  # non-interactive conversion
  ./units.sh '6 feet' 'meter'

Providing a single argument with a unit in order to select from a list of conformable ones:
```
  # semi-interactive conversion
  ./units.sh '20 liter'
```

Results are copied to clipboard, except for interactive mode where there is a menu option for doing so.
Monero (XMR) exchange rates are updated if the cached rates are older than the age (in seconds) provided in the UPDATE_THRESHOLD environment variable.
Initial updates can be disabled by setting a negative threshold (UPDATE_THRESHOLD=-1 ./units.sh).
