A thermometer is used to measure temperature.

Temperature can be measured in degrees Fahrenheit (°F) or degrees Celsius (°C).

Example:

The red line on the thermometer ends halfway between the third and fourth marks after 30°F.

Each mark on the thermometer represents 2°F.

So, the temperature shown on the thermometer is 37°F.

The short hand on a clock is called the hour hand.
It points to the number that is the hour in the time.
If the hour hand is between two numbers, the hour is
the number before the hour hand.

The long hand on a clock is called the minute hand.
There are five tick marks from one number on a clock to the next number.
Each tick mark represents one minute, so each number on the clock
represents five minutes.

In the clock above, the hour hand is on the 2, and the minute hand is on the 12.
The time shown on the clock is 2:00.

In this clock, the hour hand is a little past the 2, and the minute hand is on the 1.
The time shown on the clock is 2:05.

In this clock, the hour hand is halfway between the 2 and the 3, and the minute hand is on the 6.
The time shown on the clock is 2:30.

In this clock, the hour hand is between the 2 and the 3, but closer to the 3, and the minute hand is on the 9.
The time shown on the clock is 2:45.

Minutes after Hour	Time Terms
0	o'clock
15	quarter after quarter past
30	half past
45	quarter to

Example:

The hour hand is pointing between 8 and 9, and the minute hand is pointing to 9.
Each number on a clock represents 5 minutes.
So, the time is fifteen minutes before nine o'clock, or fifteen minutes to nine o'clock.

Fifteen minutes is one-fourth, or one-quarter, of an hour.
So, another way to write this time is quarter to nine.

The time can also be written as minutes after or past the hour.
The time is forty-five minutes after eight o'clock, or forty-five minutes past eight o'clock.

One more way to write the time is using the hour and minutes.
The time is 45 minutes after 8 o'clock, which is written as
eight forty-five.
