Good Afternoon!Today we will be learning about
Metric Units of Capacity
Let’s warm up :
Estimate length of the following in meters:
1) 185 centimeters
2) 29 decimeters
3) Convert 900 centimeters to meters
4) Convert 5 kilometers to meters
1) 2 meters
2) 3 meters
3) 9 meters
4) 5,000 meters

Let’s review what we did in the previous chapter
Centimeters (cm), millimeters (mm), decimeters (dm), and kilometers (km) are
used to measure length in the metric system.

Metric Units of Length
10 millimeters (mm) = 1 centimeter (cm)
10 centimeters (cm) = 1 decimeter (dm)
100 centimeters = 1 meter (m)
1,000 meters = 1 kilometer (km)
Simple Conversion Tables

Review
Convert meters to millimeters
To change to a smaller unit, multiply.
Example: How many millimeters is 4 meters?
We are given,
4 meter = __ millimeter 4 x 1,000 = 4,000
4 meter = 4,000 millimeter
4 meter is equal to 4,000 millimeter .

ReviewReview
Convert centimeters to meters
To change to a Larger unit, divide.
Example: How many meters is 500 centimeters ?
We are given,
500 centimeters = __ meters 500 ÷ 100 = 5
500 centimeters = 5 meters
500 centimeters is equal to 5 meters .

Estimate and measure length
To estimate and measure length of an object:
Use a centimeter ruler, meter stick or tape measure to measure objects.
Choose the appropriate Metric unit.
Estimate the length to the nearest unit with the help of the mark closest to the end of the object.
ESTIMATE: An answer that is close to the exact answer.
12 x 779 = 9,348
12 x 800 = 9,600 Estimate

Review
Estimate length of 478 centimeters in meters
478 centimeters closest to 500 centimeters.
500 centimeters = 500 ÷ 100 meters
= 5 meters
So, the estimated length of 478 centimeters is 5 meters.
