When specifying a precise duration, use "one hour". For more general references, "an hour" is often sufficient. For example, "The experiment lasted for one hour," versus, "I'll meet you in an hour."
Common error
Avoid using "an hour" when the exact duration is crucial or when emphasizing the singularity of the time period. "One hour" provides a more precise and emphatic statement.
