Expert writing Tips

Best practice

When using "per length" in technical writing, ensure the units of length are clearly stated (e.g., "per meter", "per kilometer") to avoid ambiguity.

Common error

Avoid using "per length" when "per unit" or a specific unit of measure is more appropriate. Using "cost per length" without defining the length unit (e.g., meter, foot) can lead to confusion. Always specify the length unit for clarity.

Linguistic Context

The phrase "per length" functions as a prepositional phrase, modifying nouns or clauses to specify a rate, ratio, or quantity relative to a unit of length. It is commonly used in technical and scientific contexts, as shown in the examples provided by Ludwig.

Ludwig's WRAP-UP

In summary, "per length" is a prepositional phrase used to express rates, ratios, or quantities in relation to a unit of length. Ludwig AI confirms its grammatical correctness and usability, particularly in formal and scientific contexts. While it's a common expression, remember to clearly define the units of length to avoid ambiguity. Alternatives like "for each unit of length" or "per unit length" can be used for variety, but "per length" is direct and widely understood. By specifying the units and ensuring clarity, you can effectively use "per length" in your writing.

FAQs

How do I use "per length" in a sentence?

Use "per length" to express a ratio or rate related to a unit of length. For example, "The resistance is measured in ohms per length of wire" or "The cost is $5 per length of the cable".

What is an alternative to saying "per length"?

Alternatives include "for each unit of length", "per unit length", or "with respect to length", depending on the context.

When is it appropriate to use "per length" versus "per unit"?

"Per length" is best when referring specifically to a measurement related to a linear dimension. "Per unit" is more general and can apply to any measurable quantity.

What does "mass per length" mean?
