What does lbs mean?

Pound (lb) is a unit of mass. The abbreviation lb comes from the Latin word libra, which originally meant balance or scales.
Sometimes lbs is used as an abbreviation for pounds, but lb is the correct and preferred abbreviation.
This misconception likely stems from the fact that s often indicates plural in English. However, the plural form of libra would be librae, not libras, so lbs doesn't follow standard Latin pluralization rules.
For precise and consistent usage, use lb as the abbreviation for "pound" regardless of quantity.

Example:
Instead of saying 7 lbs, you should write 7 lb or 7 pounds.
