//! US Customary units of mass.
//!
//! This module contains predefined newtypes for units of mass as defined in the
//! US Customary system. The base unit is the metric kilogram.
//!
//! Since the US Customary system is the same as the British Imperial system for
//! mass up to the pound (included), reexports from the `imperial` module are
//! used, where possible.
