How to Convert Units of Time

Do you remember how long it takes for the minute hand to travel all the way around the clock? Yes, it takes 60 minutes or one hour for the minute hand to travel all the way around the clock. What about the second hand? How long does it take to move around the clock? It takes one minute for the second hand to travel around the clock. So, there are 60 seconds in one minute.

Now let’s look at the hour hand. It takes 60 minutes, or one hour, to travel between numbers. There are 12 hours on the clock. On a clock like this, the hour hand travels to each number twice in one day. That’s why we have 7 o’clock in the morning and 7 o’clock in the evening. That means there are 24 hours in one day.
