Why Is Pounds Abbreviated To Lbs? This question often pops up when we encounter the seemingly illogical abbreviation ‘lbs’ for ‘pounds’. At WHY.EDU.VN, we will explore the fascinating history of weights and measures to uncover the answer. The evolution of language and historical measurement practices reveal the hidden connection between ‘pounds’ and ‘lbs’, offering insights into historical linguistics and metrology.
1. The Roman Connection: Libra Pondo
The abbreviation ‘lb’ for pound originates from ancient Rome. The Romans used the term “libra pondo” to denote “a pound by weight”. The term ‘libra’ referred to a unit of weight, and ‘pondo’ meant ‘by weight’.
1.1. Libra: More Than Just a Weight
‘Libra’ was not solely a unit of weight; it also served as a basis for currency. The British pound’s symbol, £, is derived from ‘libra’.
1.2. The British Pound Sterling
The British pound sterling is a testament to the enduring legacy of the ‘libra’. Its value originally corresponded to the price of a pound of silver.
2. Linguistic Evolution: From Latin to English
The transition from ‘libra pondo’ to ‘lb’ involves the fascinating evolution of language and measurement systems. Here is a table summarizing the key stages:
| Stage | Language | Term | Meaning |
|---|---|---|---|
| Ancient Rome | Latin | Libra Pondo | A pound by weight |
| Medieval Europe | Latin | Libra | Unit of weight |
| Modern English | English | Pound | Unit of weight/currency |
| Abbreviation | English | Lb | Abbreviation for pound |
This linguistic journey highlights how ancient terms have been adopted and adapted over centuries, shaping the measurement systems we use today.
3. The Ounce and Its “Z”: A Medieval Tale
While ‘lb’ traces back to ‘libra’, the abbreviation ‘oz’ for ounce has a different origin. The word ‘ounce’ comes from the Latin ‘uncia’, a Roman unit of weight and length.
3.1. Uncia: The Roman Root
‘Uncia’ represented one-twelfth of a ‘libra’. This fraction was significant in Roman commerce and daily life, making ‘uncia’ a commonly used term.
3.2. Anglo-Norman Influence
Following the Norman invasion of England in 1066, Anglo-Norman French transformed ‘uncia’ into ‘ounce’. This linguistic shift marked a crucial step in the word’s evolution.
3.3. The Italian “Onza”
The ‘z’ in ‘oz’ comes from medieval Italian, where ‘uncia’ became ‘onza’. The abbreviation ‘oz’ reflects this Italian influence, preserving the ‘z’ in English usage.
4. Why “Lbs” Instead of “Lb”? Pluralization in Abbreviations
The use of “lbs” as the plural abbreviation for pounds is a common point of confusion. While “lb” is the standard abbreviation for both singular and plural forms, “lbs” is often used informally.
4.1. Grammatical Considerations
In formal writing, abbreviations for units of measurement typically do not change in the plural form. For example, “5 kg” is correct, not “5 kgs.”
4.2. Common Usage and Acceptance
Despite the grammatical rule, “lbs” is widely used and accepted in many contexts. This acceptance stems from a desire for clarity and ease of understanding.
