We know that the measurement of time is read by a watch or a clock.

Every watch except a digital watch has a dial. The hour numbers from 1 to 12 are equally spaced on the circular edge of the face of a clock. There are five divisions between the two numbers. Each department represents one minute.


There are two hands of different lengths with one of the ends attached to the center of the dial. The The small hand is the hour hand and The longer hand is the minute hand. The hour hand moves more slowly than the minute hand. There is also a third hand called the second hand. It moves very quickly.

The hour hand makes one lap on the dial in 12 hours. It moves from one number to the next in an hour, i.e. the hour hand goes from 12 to 1 or 1 to 2 or 2 to 3 etc. in an hour.

The minute hand makes one lap on the dial in 1 hour. It moves across a division in one minute or five divisions in 5 minutes.

If there is a second hand, it makes one lap on the dial in one minute, that is, it moves across a division in one second.

On this basis we say:

1 hour = 60 minutes or 60 minutes = 1 hour

1 minute = 60 seconds or 60 seconds = 1 minute

1 hour = 60 minutes = 60 x 60 or 3600 seconds

We know that the dial of the watch is marked with the numbers 1 through 12, which divide the dial into 12 equal parts. These 12 parts are further divided into 60 small sections. So there are 5 small divisions between any two numbers on the dial. The minute hand takes 5 minutes to move from one number to the next. We have learned to read the time to the nearest 5 minutes.
