Pounds abbreviate to "lb" and ounces to "oz". This originates from the Latin language. The pound's abbreviation "lb" comes from the Latin word "libra". The Latin phrase "libra pondo" roughly translates to "a pound by weight". Our abbreviation "lb" is derived from these two words. Similarly, the abbreviation for ounces, "oz", comes from the Italian word "onza". Today, these symbols are used all over the world and they're universally recognized in business, commerce, and industries like food preparation and postal services, just to name a few!
