1. The Roman Influence: Libra Pondo
The abbreviation “lb” for pound traces back to ancient Rome. The Romans used the term “libra pondo,” which translates to “a pound by weight” in Latin. This phrase consisted of two key components: “libra,” referring to a unit of weight, and “pondo,” indicating “by weight.”
1.1. Libra: More Than Just a Sign
If “libra” sounds familiar, it’s because it’s also the name of the seventh sign of the zodiac, often symbolized by scales. This association isn’t coincidental. Libra represents balance and is intrinsically linked to weights and measurements, underscoring its historical significance in quantifying weight.

1.2. Pondo: The Root of “Pound”
While “lb” comes from “libra,” the English word “pound” is derived from “pondo.” The linguistic evolution from “pondo” to “pound” is a straightforward example of how words transform over time, adapting to different languages and cultures.
2. From Libra to Lb: A Historical Journey
The transition from “libra” to “lb” as the abbreviation for pound wasn’t arbitrary. It was a deliberate choice rooted in the historical importance of “libra” as a unit of weight in Roman society.
2.1. The Symbol £: Another Libra Derivative
Interestingly, the symbol for the British pound (£) also originates from “libra.” The pound’s value was historically equivalent to the price of a pound of silver. The “L” with a line through it represents “libra,” further cementing the Roman unit’s legacy in modern currency and measurement.
2.2. Lira: Echoes of Libra in Currency
The influence of “libra” extends beyond the British pound. The former Italian currency, the lira, also derived its name from “libra,” demonstrating the widespread impact of Roman measurement systems on European monetary systems.
3. Ounce: A Companion Measurement
While exploring the abbreviation of pounds, it’s also worth understanding the origin of “oz” for ounce. An ounce is 1/16 of a pound, and its abbreviation has a unique history.
3.1. Uncia: The Latin Origin of Ounce
The word “ounce” comes from the Latin word “uncia,” which was a Roman unit of both weight and length. This term was versatile, used in various contexts to measure small quantities.
3.2. From Uncia to Oz: A Linguistic Twist
The transformation of “uncia” to “oz” involves several linguistic steps. The Anglo-Norman French language, which developed in England after the Norman invasion in 1066 C.E., converted “uncia” into “ounce.” The “z” in “oz” comes from medieval Italian, where “uncia” became “onza.” This “z” stuck around in the English abbreviation, adding a unique twist to its etymology.
4. Why Not “Pd”? Avoiding Ambiguity
One might wonder why “pd” isn’t used as the abbreviation for pound, given that “pound” starts with “p.” The reason is to avoid confusion with other units and terms that might also use “pd.”
4.1. Clarity in Measurement
Using “lb” provides a clear, unambiguous reference to the Roman “libra,” ensuring that it isn’t mistaken for other measurements or abbreviations. This clarity is crucial in scientific, commercial, and everyday contexts.
4.2. Historical Precedence
The historical precedence of “lb” as the abbreviation for pound has also solidified its use over time. Once a standard is established, it tends to persist due to familiarity and ease of understanding.
5. Pounds Across Different Systems
Pounds are primarily used in the imperial measurement system, which is common in the United States and some other countries. Understanding its relationship with the metric system is essential for global contexts.
5.1. Imperial vs. Metric
In the metric system, the equivalent of pounds is kilograms. One kilogram is approximately equal to 2.2 pounds. This conversion is important for international trade, scientific research, and other areas where both systems are used.
5.2. Usage in Various Countries
While the metric system is more prevalent worldwide, pounds remain a common unit of weight in the United States and the United Kingdom. Knowing how to convert between pounds and kilograms is a valuable skill in today’s globalized world.
6. The Plural of Lb: Lb or Lbs?
A common question is whether the plural abbreviation of pound is “lb” or “lbs.” The general rule is that abbreviations for measurements do not change in the plural form.

According to most style guides, the correct abbreviation for both one pound and multiple pounds is “lb.” Adding an “s” is generally considered incorrect in formal writing.
6.2. Accepted Usage
However, it’s worth noting that some guidelines and informal contexts accept “lbs” as correct. This usage is more common in everyday language and less formal settings.
