quarter of an hour
Fourth of sixty
A quarter of an hour is fifteen minutes—one fourth of a sixty-minute hour.
The phrase appears in time expressions where precision matters but exactness doesn't: I'll be ready in a quarter of an hour.
It sounds slightly more formal or British than "fifteen minutes."
