The abbreviation lb has an interesting history.

It comes from the Latin word libra, which meant:

• A balance

The phrase libra pondo meant a pound by weight.

Over time:

1. Latin: libra pondo
2. Old French influence
3. Middle English adoption of pound
4. Abbreviation remained lb

The letter s was later added to create the plural abbreviation lbs.

This explains why the abbreviation looks completely different from the word pound.
