 This module provides localized measurement unit formatting.
 
 `Units.format` supports the following arguments:
 - `amount`: the amount associated with the unit. This parameter is used to apply the unique pluralization rules of the requested locale.
-- `unit`: the measurement unit. Currently, only the keys listed in [`Worldwide::MEASUREMENT_KEYS`](https://github.com/Shopify/worldwide/blob/main/lib/worldwide/units.rb#L9-L51) are supported.
+- `unit`: the measurement unit. The keys listed in [`Worldwide.Units.measurement_keys`](https://github.com/Shopify/worldwide/blob/main/lib/worldwide/units.rb#L23-L70) are supported.
 - `humanize`: can be `:long` or `:short`. `:long` returns the translated word of the unit. `:short` returns the localized abbreviation of the unit. The default value is `:short`.
 
 ```ruby
 # To display the abbreviated version of the unit
 $ Worldwide.units.format(5, :kilogram)
