Difference Between 'A Cup of Coffee' and 'One Cup of Coffee'

The commonality between 'a cup of coffee' and 'one cup of coffee' is their grammatical structure.

However, there is a subtle yet important difference in the contextual usage and the level of politeness conveyed by each phrase.

However, in a different context, 'one' might be used more precisely to avoid confusion, such as in "Give me one cup of coffee and two cups of tea" in a situation where there might be multiple orders to clarify.

Contextual Usage and Politeness in English

Using 'one cup of coffee' would be perceived as more formal and may come across as awkward.
