用法筆記
The abbreviation 'lb' comes from Latin 'libra pondo' ('pound weight'). The 'libra' part gave us the abbreviation, while 'pondo' became the English word 'pound'. The plural is usually written the same way ('lb'), though 'lbs' is also common in informal contexts. In formal academic writing, use the full word 'pound(s)' instead.
