--- title: units() --- ```js string utils.units(float value, string format = 'metric') ``` Converts the units `value` you pass it into a formatted string for the `format` you pass it. Format must be either `imperial` or `metric` (the default). The [Part.shorthand](/reference/api/part/shorthand/) call provides a context-aware `unit()` method that will call this method and pass it the units requested by the user.
