### Text of Meters, Grams and Liters

• Meters, Grams and Liters

• The Metric SystemThe metric system is a measurement system based on our decimal (base 10) number system.

Other countries and all scientists and engineers use the metric system for measurement.

• Metric Prefixes

Metric UnitsThe metric system has prefix modifiers that are multiples of 10.

• Place Values of Metric Prefixes

• MetersMeters measure length or distanceOne millimeter is about the thickness of a dime.

• MetersOne centimeter is about the width of a large paper clip

• MetersA meter is about the width of a doorway

• MetersA kilometer is about six city blocks or 10 football fields.

1.6 kilometers is about 1 mile

• GramGrams are used to measure mass or the weight of an object.

• GramsA milligram weighs about as much as a grain of salt.

• Grams1 gram weighs about as much as a small paper clip.

1 kilogram weighs about as much as 6 apples or 2 pounds.

• LitersLiters measure liquids or capacity.

• Liter1 milliliter is about the amount of one drop

• Liter1 liter is half of a 2 liter bottle of Coke or other soda

• LiterA kiloliter would be about 500 2-liter bottles of pop

• Which unit would you use to measure the distance across Kansas? kmmcmmL

• Which unit would you use to measure the height of a tree? kmmcmmm

• Which unit would you use to measure the length of a bracelet? kmmcmmm

• Changing Metric UnitsTo change from one unit to another in the metric system you simply multiply or divide by a power of 10.

• To change from a larger unit to a smaller unit, you need to multiply.1 km x 1000 = 1000 m1 m x 100 = 100 cm1 cm x 10 = 10mm

• Place Values of Metric PrefixesMove the decimal point to the right to multiply.

• Place Values of Metric Prefixes

• To change from smaller units to larger units you divide by a power of ten.1000mm 10 = 100cm100cm 10 = 10dm10dm 10 = 1m

• Place Values of Metric PrefixesMove the decimal point to the left to divide.

• Place Values of Metric Prefixes

• Sorry!That is not the BEST choice!
