The Metric System
A simple way to measure
What is it???
A system of measurement based on multiples of 10
010.010.1
000.001
Each Multiple has its own name
Milli = 0.001 or 1/1000
Deca = 10
Centi = 0.01 or 1/100
Deci = 0.1 or 1/10
= 1 (no prefix)
Each Multiple has its own name
Hecto = 100
Kilo = 1000
Length – “the Meter”How long is something? We use the Meter to measure
the length of objects
A meter is almost equal to a yard in the English System
* 1 yard= .9144 meter, 1 m = 3.28 feet, 1 yard = 3 feet
The Meter Comes in Different Sizes
Millimeter Centimeter Meter Kilometer
1 inch = 25.4 mm 1 mile = 1.6 km 1 m = 3.28 ft 1 inch = 2.54 cm
1 Centimeter
10 Millimeters
1mm1mm 1mm 1mm 1mm 1mm 1mm 1mm 1mm 1mm
Is the same as
1 Meter
100 CentimetersIs the same as
100 Centimeters
1000 Millimeters
Which is the same as
1 MeterIs the same as
1 Kilometer
1000 MetersIs the same as
Need to Know!!!!
10 mm = 1 cm 100 cm = 1 m 1000 m = 1 km
1000 mm = 100 cm 1000 mm = 1 m
How many mm = 1 km ???
The “Need to Know” on the previous slide holds true for EVERY unit of measurement in the metric system! You can substitute in gram for meter, or liter for gram… all three have the same exact conversions!
Keep this in mind as you continue through the presentation!
Mass – “the Gram”
Mass is a measure like weight, or how heavy something is.
Measurement like ounces and pounds. The gram is closest to an ounce in the
English System of measurement(1 ounce weighs about the same as a slice of bread,
1 gram = about one paperclip!)
The gram comes in different sizes too!
Milligram gram kilogram
1 oz = 28.35 grams 1 pound = 2.2 kg
Volume – “the Liter”
Volume tells how much space an object takes up
Used to measure liquids Measurement like cups, ounces and
gallons The liter is closest to a quart in the
English System of measurement(1 liter = 1.056 quarts, 1 quart = 4 cups)
The Liter comes in different sizes like the meter and gram!
Milliliter Liter Kiloliter
1 gallon = 3.78 liters5 ml = 1 teaspoon = 1 cc
