Alfred-Convert

Convert between different units offline in Alfred 3 & 4.

Alfred-Convert uses a built-in library for lightning-fast conversions.

You can also add your own custom units.

Note: Currency conversions do require occasional Internet connectivity to update exchange rates. Alfred-Convert will otherwise work just fine without an Internet connection.

Downloading

Download from GitHub releases.

Note: Version 3.7 and above only supports Alfred 4+. If you're still using Alfred 3, please download v3.6.2.

Usage

  • conv   []
    — Perform a conversion
    • — Copy result without thousands separator to pasteboard
    • ⌘C
      — Copy result with thousands separator to pasteboard
    • ⌘↩
      — Add/remove destination unit as default for this dimensionality
    • ⌘L
      — Show result in Alfred's Large Type window
  • convinfo
    — View help file and information about the workflow, or edit custom units and active currencies
    • View Help File
      — Open this page in your browser
    • View All Supported Currencies
      — View/filter the list of all supported currencies in Alfred

Conversions

NOTE: Only a limited number of fiat currencies are supported by default. Additional rates are only supported if you set a key for the openexchangerates.org API in the workflow's configuration sheet. You can sign up for a free account here. When you're signed up, copy the App ID from the email you receive or this page into the

APP_KEY
field in the configuration sheet.
  • conv []   []
    — Perform a conversion
    • or
      ⌘C
      — Copy the result to the pasteboard
    • ⌘↩
      — Add/remove destination unit as default for this dimensionality
    • ⌘L
      — Show result in Alfred's Large Type window

If no destination unit is specified, any defaults you've saved will be used (that aren't the same as the source unit).

The syntax is simple: an optional context, the quantity, the unit you want to convert from then (optionally) the unit you want to convert to. For example:

  • conv 128 mph kph
  • conv 72in cm
  • conv 100psi bar
  • conv 20.5 m/s mph
  • conv 100 eur gbp

Or with a context:

  • conv spectroscopy 1Å eV
    (or
    conv sp 1Å eV
    )

It doesn't matter if there is a space between the quantity and the units or not. Alfred-Convert will tell you if it doesn't understand your query or know the units.

Actioning an item (selecting it and hitting

) will copy it to the clipboard. Using
⌘+L
will display the result in Alfred's large text window,
⌘+C
will copy the selected result to the clipboard.

Configuration

The workflow is configured via the configuration sheet (the

[𝒙]
icon) in Alfred Preferences and via a couple of text files in its data directory.

Configuration sheet

Basic configuration is performed in the configuration sheet:

| Option | Meaning | |---------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------| |

APP_KEY
| API key for openexchangerates.org. | |
COPY_UNIT
| Include unit when copying conversion result. Any value but
0
or empty turns this option on. | |
CURRENCY_DECIMAL_PLACES
| Overrides the default
DECIMAL_PLACES
setting for currency conversions. | |
DECIMAL_PLACES
| Number of decimal places to show in results. | |
DECIMAL_SEPARATOR
| Character to separate whole numbers and decimal fractions. Used for parsing input and generating output. | |
DYNAMIC_DECIMALS
| Dynamically increase the number of decimal places (up to 10) so that the result is non-zero. Any value but
0
or empty turns this option on. | |
THOUSANDS_SEPARATOR
| Character to delimit thousands Used for parsing input and generating output. | |
UPDATE_INTERVAL
| How often (in minutes) to update currency exchange rates. |

Active currencies

By default, all supported fiat currencies (provided you've set

APP_KEY
in the configuration sheet) and a handful of the most popular cryptocurrencies are active.
  • convinfo
    • View All Supported Currencies
    • Edit Active Currencies

Use

Edit Active Currencies
to open the list of active currencies in your default editor. Add the symbol for the currency you'd like to activate on a new line in this file.

You can use

View All Supported Currencies
to search for the currency you'd like to activate, then use
⌘C
on the result to copy the symbol to the pasteboard.

Custom units

See Adding custom units.

Supported units

Currently, Alfred-Convert only supports the units understood by the underlying Pint library plus currencies and a handful of additional units.

You can add your own custom units to the workflow. If you think they'd be useful to everyone, please create a corresponding GitHub issue to request addition as a default unit or submit a pull request.

Supported currencies

To convert, use the appropriate abbreviation for the relevant currencies, e.g.

conv 100 eur gbp
.

You can also view (and search) the list from within Alfred by using the keyword

convinfo
and choosing
View All Supported Currencies
.

All supported currencies.

Adding custom units

You can add your own custom units using the format defined by Pint. Add your definitions to the

unit_definitions.txt
file in the workflow's data directory.

To edit this file, enter

convinfo
in Alfred and select
Edit Custom Units
. The
unit_definitions.txt
file will open in your default text editor.

Please see the Pint documentation for the required format. See Pint's default unit definitions for examples.
