Best practice

When describing the size of circular objects, always specify the units of measurement (e.g. mm, cm, inches) to avoid ambiguity. If you're describing a sphere, use "diameter" instead of "radius".

Common error

Avoid omitting the unit of measurement or using an incorrect unit. For example, do not write "the circle is 5 in diameter" without specifying "mm" or "cm".

Linguistic Context

The phrase "mm in diameter" functions as a post-modifier to a noun, specifying its size. It provides a precise measurement of the width of a circular or cylindrical object. As seen in Ludwig, it's commonly used in scientific and technical contexts to define dimensions.
