# GNU Units Skill Use GNU `units` to perform unit conversions and calculations via the command line. Can be installed using brew and apt under "units". ## Usage Use the `bash` tool to run the `units` command. Use the `-t` (terse) flag to get just the numeric result. ```bash units -t 'from-unit' 'to-unit' ``` ### Examples **Basic Conversion:** ```bash units -t '10 kg' 'lbs' # Output: 22.046226 ``` **Compound Units:** ```bash units -t '60 miles/hour' 'm/s' # Output: 26.8224 ``` **Temperature (Non-linear):** Temperature requires specific syntax: `tempF(x)`, `tempC(x)`, `tempK(x)`. ```bash units -t 'tempF(98.6)' 'tempC' # Output: 37 ``` **Time:** ```bash units -t '2 weeks' 'seconds' ``` **Rounding Output:** To round to specific decimal places (e.g. 3 places), use `-o "%.3f"`: ```bash units -t -o "%.3f" '10 kg' 'lbs' # Output: 22.046 ``` **Definition Lookup:** To see what a unit definition is (without converting), omit the second argument (without `-t` is more verbose/useful for definitions): ```bash units '1 acre' ``` ## Notes - **Currency:** `units` supports currency (USD, EUR, etc.), but exchange rates may be out of date as they are static in the definitions file. - **Safety:** Always quote your units to prevent shell expansion issues (e.g. `units -t '1/2 inch' 'mm'`).
