CONFIDENTIAL 1 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

CONFIDENTIAL2 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. 1 cm 1 mm 1 dm

CONFIDENTIAL3 Review 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

CONFIDENTIAL4 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.

CONFIDENTIAL5 Review 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 = centimeters = 5 meters 500 centimeters is equal to 5 meters.

CONFIDENTIAL6 Review 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, x 800 = 9,600 Estimate

CONFIDENTIAL7 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.

CONFIDENTIAL8 Today we will learn about the Metric Units of Capacity Capacity: A measure of a dry or liquid volume of a container. Ounces are customary units of measurement. Milliliters are metric units.

CONFIDENTIAL10 Metric Units of Capacity 1,000 milliliters (ml) = 1 liter (L) Simple Conversion Tables

CONFIDENTIAL11 Convert liters to milliliters To change to a smaller unit, multiply. Example: How many milliliters is 4 liters? We are given, 4 liters = __ milliliters 4 x 1,000 = 4,000 4 liters = 4,000 milliliters 4 liters is equal to 4,000 milliliters.

CONFIDENTIAL12 Convert milliliters to liters To change to a Larger unit, divide. Example: How many liters is 5,000 milliliters ? We are given, 5,000 milliliters = __ liters 5,000 ÷ 1000 = 5 5,000 milliliters = 5 liters 5,000 milliliters is equal to 5 liters.

CONFIDENTIAL13 Convert liters to milliliters To change to a smaller unit, multiply. Example: How many milliliters is 7 liters? We are given, 7 liters = __ milliliters 7 x 1,000 = 7,000 7 liters = 7,000 milliliters 7 liters is equal to 7,000 milliliters.

CONFIDENTIAL14 Convert milliliters to liters To change to a Larger unit, divide. Example: How many liters is 12,000 milliliters ? We are given, 12,000 milliliters = __ liters 12,000 ÷ 1000 = 12 12,000 milliliters = 12 liters 12,000 milliliters is equal to 12 liters.
