When it comes to journalism and professional writing, adhering to a consistent style guide ensures clarity and credibility. The Associated Press (AP) Stylebook is one of the most widely used style guides in the United States, especially among journalists and media outlets. One common question that writers often face is how to correctly write the abbreviation for pounds, commonly represented as "lbs." This guide will walk you through the correct AP Style approach to writing "lbs," including its abbreviation, usage, and common mistakes to avoid.
Understanding AP Style and Its Importance
The AP Stylebook provides specific rules for writing numbers, abbreviations, and units of measurement to maintain clarity and uniformity across news articles and reports. Proper adherence to these rules helps readers easily understand information without confusion or ambiguity. When it comes to weight measurements, the AP Stylebook has clear guidelines that writers should follow for consistency and professionalism.
How To Write "Lbs" in AP Style
In AP Style, the abbreviation for pounds is "lb." When referring to multiple pounds, the plural abbreviation is "lbs." However, it is important to note that AP Style prefers not to use the abbreviation "lbs" unless necessary, especially in more formal or technical writing. Instead, the style recommends spelling out the word "pounds" in most cases, especially in journalistic writing. Here are the key points:
- Use "lb" as the abbreviation for a single pound when necessary.
- Use "lbs" as the plural abbreviation for multiple pounds.
- Always lowercase and do not add a period after "lb" or "lbs."
- When used with a number, include a space between the numeral and the abbreviation (e.g., 5 lb, not 5lb).
- In most cases, spell out "pounds" instead of abbreviating, especially in formal writing.
Proper Usage and Examples in AP Style
Here are some examples illustrating the correct way to write weight measurements in AP Style:
- Correct: The package weighs 10 lb.
- Correct: The dog weighs 50 lbs.
- Correct: She lost 15 pounds during the challenge.
- Incorrect: The box weighs 10lbs.
- Incorrect: The bag is 5 LBS.
- Incorrect: The athlete lifted 200 lbs.
Note that when writing in AP Style, you should include a space between the number and the abbreviation: "5 lb" or "50 lbs." Avoid using periods after "lb" or "lbs," and do not capitalize the abbreviation unless it begins a sentence.
When to Spell Out "Pounds"
While abbreviations are useful in technical writing or space-constrained contexts, AP Style generally favors spelling out "pounds" in narrative or formal text. Here are some guidelines:
- Use "pounds" in full in most articles for clarity and readability.
- Spell out "pounds" when the measurement appears in the middle of a sentence or in formal writing.
- Use abbreviations "lb" or "lbs" primarily in tables, charts, or when space is limited.
Examples:
- The patient gained 20 pounds during the pregnancy.
- The package weighs 8 lb.
Common Mistakes to Avoid
To ensure your writing aligns with AP Style, steer clear of these common errors:
- Using "lbs" without a preceding number or context (e.g., just "lbs" alone).
- Adding a period after "lb" or "lbs" (e.g., "lb." or "lbs.").
- Using uppercase "LBS" or "Lbs" — AP Style prefers lowercase.
- Using "lbs" without a space after the number (e.g., "10lbs" instead of "10 lbs").
- Overusing abbreviations in formal or narrative writing where spelling out "pounds" would be clearer.
Additional Tips for Writing Measurements in AP Style
Beyond pounds, AP Style has specific rules for other measurements and abbreviations:
- Always spell out measurements when they are used as adjectives before a noun (e.g., "a 10-pound bag").
- Use figures for measurements above 10 (e.g., "12 inches," "15 pounds").
- Include a space between the number and the abbreviation or measurement unit (e.g., "5 ft," not "5ft").
- Use lowercase for units of measurement (e.g., "kg," "cm," "oz").
Summary of Key Points
- In AP Style, use "lb" for singular and "lbs" for plural when abbreviating pounds.
- Always include a space between the number and the abbreviation (e.g., "10 lb," "50 lbs").
- Generally, spell out "pounds" in formal writing and in the body of articles.
- Avoid periods after "lb" and "lbs."
- Follow AP Style rules for other measurements for consistency.
