How long is 3 minutes?

3 minutes converts to 180 seconds, or exactly 1/20 of an hour. That is roughly 0.2% of a 24-hour day. Half of 3 minutes is 1 minute 30 seconds, and two rounds back to back add up to 6 minutes.

Three minutes is the classic steep for green tea and roughly the length of a pop song.
