19. Length
The standard unit of length in the metric system is the meter. Other units of length and their equivalents in meters are as follows:
1 millimeter = meter 1 centimeter = 0.01 meter 1 decimeter = 0.1 meter 1 kilometer = 1000 meters
We symbolize these lengths as follows: 1 millimeter = 1 mm 1 centimeter = 1 cm 1 meter = 1 m 1 decimeter = 1 dm 1 kilometer = 1 km
For reference, 1 meter is a little longer than 1 yard or 3 feet. It is about half the height of a very tall adult. A centimeter is nearly the diameter of a dime, a little less than half an inch. A millimeter is about the thickness of a dime.

20. Mass standard unit in the metric system is the gram.
Other units of mass and their equivalents in grams are as follows: 1 milligram = gram 1 centigram = 0.01 gram 1 decigram = 0.1 gram 1 kilogram = 1000 grams
We symbolize these masses as follows: 1 milligram = 1 mg 1 centigram = 1 cg 1 decigram = 1 dg 1 gram = 1 g 1 kilogram = 1 kg
For reference, 1 gram is about the mass of a paper clip.
One kilogram is about the mass of a liter of water.

21. Volume
The standard unit of volume in the metric system is the liter.
One liter is equal to 1000 cubic centimeters in volume.
Other units of volume and their equivalents in liters are as follows: 1 milliliter = liter 1 centiliter = 0.01 liter 1 deciliter = 0.1 liter 1 kiloliter = 1000 liters
From these units, we see that 1000 milliliters equal 1 liter;
so 1 milliliter equals 1 cubic centimeter in volume.
We symbolize these volumes as follows: 1 milliliter = 1 ml 1 centiliter = 1 cl 1 deciliter = 1 dl 1 liter = 1 l 1 kiloliter = 1 kl
For reference, 1 l is a little more than 1 quart. One teaspoon is about 5 milliliters.

22. Temperature is expressed in degrees Celsius in the metric system
Temperature is expressed in degrees Celsius in the metric system. The boiling point of water (at sea level) is 100°Celsius, or 100°C. The freezing point of water (at sea level) is 0° Celsius. A hot day is about 30° Celsius.
