Alfred unit converter is a smart calculator for Alfred with support for unit conversions to make it a bit comparable to the Google Calculator and Wolfram Alpha.

Issues

If new units and/or other names for units should be added please let me know by creating an issue at: https://github.com/WoLpH/alfred-converter/issues

Installation

Configuration

The extension can be configured through the environment variables setting in Alfred.

::

BASE_2: Enable base 2 (binary ) output
BASE_8: Enable base 8 (octal) output
BASE_16: Enable base 16 (hexadecimal) output
DECIMAL_SEPARATOR: Comma or dot separator for decimals
FRACTIONAL_UNITS: "both", "decimal" or "fractional" only
MAX_MAGNITUDE: Maximum orders of magnitude to show. For 1 megabyte in bytes we need 9 orders of magnitude because it's 1 million bytes.
UNITS_BLACKLIST: Units you wish to hide
UNITS_SIDE: Showing the units at the right or the left side
