Abbreviating Pounds: Understanding lb, lbs, and Their Punctuation in US and UK Standards
Introduction to Pounds and Their Abbreviations
Pounds are a unit of weight commonly used in both the US and UK. Abbreviating this measurement can lead to some confusion, especially regarding usage, punctuation, and legal standards. This article will explore the correct ways to abbreviate pounds, including the usage of lb and lbs, and the rules surrounding punctuation in both the United States and United Kingdom.
General Rules for Abbreviating Pounds
When presenting abbreviations in written text, it is generally customary to include a period. For instance, when referring to a single pound, the abbreviation is written as ldquo;lb.rdquo; With the plural form, it is written as ldquo;lbs.rdquo; The inclusion of the period in these abbreviations is common but not universal.
In terms of pluralization, abbreviations usually do include an rsquo;srsquo; to indicate more than one pound. Therefore, the plural would be written as ldquo;lbs.rdquo; However, if the abbreviation is regarded as a symbol rather than a written word, the period is not required, and no pluralization is performed.
US Standards for Abbreviating Pounds
The United States National Institute of Standards and Technology (NIST) recommends the following style for abbreviating pounds:
lb (lowercase, no period, no pluralization, except when ending a sentence)This style follows the recommendations of the International System of Units (SI) for symbols and abbreviations. However, for labeling net contents, the Food and Drug Administration (FDA) and the Federal Trade Commission (FTC) allow for some flexibility:
lb (lowercase, no period, no pluralization) LBS (uppercase, period, pluralization) lbs (lowercase, period, pluralization)Ultimately, the choice among these options can vary, but I adhere to the NIST style due to its consistency and alignment with SI standards.
UK Standards for Abbreviating Pounds
In the United Kingdom, pounds are not considered a legal unit of trade, which means there are no formal abbreviations or punctuation rules set by official regulatory bodies for this unit.
Other Considerations
When writing ldquo;lbrdquo; (or ldquo;lbsrdquo;), it is customary to insert a period because it is a real abbreviation rather than a symbol. This period is read ldquo;pointrdquo; and it breaks the flow of reading, so the plural form ldquo;lbsrdquo; is often used to avoid this separation.
To sum up, the abbreviation for pounds follows a few key guidelines in both the US and UK, but there is flexibility within the US, especially for net contents labeling. Always ensure your usage aligns with the target audience and the standards of the region you are writing for.
