Understanding Rotational Speed: How Many Rotations Does a Minute Hand Complete in 24 Hours? Have you ever wondered just how fast a clock’s minute hand moves? At first glance, it might seem like a steady sweep across the dial, but the minute hand actually rotates multiple times within just 24 hours. Let’s break down the surprising math behind this: in 24 hours, the minute hand completes 720 full rotations — that means roughly 30 rotations per hour. ### The Math Behind the Minute Hand’s Speed To understand the minute hand’s motion, consider how clocks work. The second hand completes one full rotation every 60 seconds. Since there are 60 minutes in an hour, this gives 60 rotations per hour — but the minute hand covers one entire circle (360 degrees) per minute, meaning it rotates 60 times in one hour — 60 minutes × 1 rotation per minute = 60 rotations/hour.
