2 3 One decimeter = 1/10 meter One dekameter = 10 meters One decigram = 1/10 gram One dekagram = 10 grams Conversion Chart One deciliter = 1/10 liter Conversion Chart One dekaliter = 10 liters Metric Units Notes 4 What does this mean? When converting metric units of measurement, we use powers of 10. 9,000 9,000 5 6 Key ideas: ● Bigger Units to smaller Units: MULTIPLY ● Smaller Units to Bigger Units: DIVIDE ● **Use the Conversion Chart!!** 7 Conversion Chart: Units of Length (Metric) 9 Units of Length (Metric) Definition: The distance between two points. ⊸ Centimeter (cm), Decimeters (dm), Meters (m), kilometers (km) 10 Units of Length 11 Examples: Meters Centimeters ➔ To convert from meters to centimeters, you must 1 100 multiply by 100. 2 200 ➔ To convert from centimeters to meters, you 3 ? must divide by 100. 4 ? Meters Kilometers ➔ To convert from meters to 1,000 1 kilometers, you must divide by 1,000. 3,000 3 ➔ To convert from 5,000 ? kilometers to meters, you must multiply by 1,000. ? 7 12 To start with #1, take a look at the chart on the right. There’s 2 meters and you want to find how many centimeters there are. You first have to multiply the amount of meters there are by 100 centimeters. 2 x 100 = 13 For the other two questions, you are using a different unit. Be careful when converting. 200 3 x _? = ________ ? x _? = ________ 14 Here, is the finished solution for the questions. Check your work once finished. 200 3 x 10 = ________ 5 x _10 = ________ 30 50 Mass and Liquid Volume 16 Mass (Weight) Mass Definition: The weight of an object. ⊸ Kilograms (kg), Grams (g), Milligrams (mg) 17 Units of Mass (Weight) 18 Examples: Grams Centigrams ➔ To convert from grams to centigrams, you must 4 400 multiply by 100. 5 500 ➔ To convert from centigrams to grams, you must divide 6 ? by 100. ? 700 Grams Kilograms ➔ To convert from grams to 5,000 5 kilograms, you must divide by 1,000. 7,000 7 ➔ To convert from 9,000 ? kilograms to grams, you must multiply by 1,000. ? 6 19 Examples: Try these on your own! 20 Liquid Volume (Capacity) Liquid Volume Definition: The capacity of an object (how much liquid it can hold). ★ Liters (L), Kiloliters (kL), Hectoliters (hL), Dekaliters (daL), Deciliters (dL), Centiliters (cL), Milliliters (mL) 21 Units of Capacity/Liquid Volume 22 Examples: Liters milliliters ➔ To convert from liters to Milliliters, you must 1 1,000 multiply by 1,000. 2 2.000 ➔ To convert from milliliters to liters, you must divide by 3 ? 1,000. ? 4,000 Liters Hectoliters ➔ To convert from Liters to 100 1 hectoliters, you must divide by 100. 300 3 ➔ To convert from 500 ? hectoliters to liters, you must multiply by 100. ? 7 23 Examples: Try these on your own! Units of Time 25 Units of Time Definition: ⊸ Seconds, Minutes, Hours, Days, Weeks, Months 26 Units of Time ⊸ To convert from minutes to seconds, you must multiply by 60 ⊸ To convert from seconds to minutes, you must divide by 60 ⊸ To convert from days to weeks, you must multiply by 7. ⊸ To convert weeks to days, you divide by 7. 27 Examples: Try these on your own! Mixed Measures 29 Mixed Measures In mixed measures, you MUST have the same unit of measurement before you can combine the measures. For example: 1 meter + 1 dekameter = 1 meter + 10 meters = 11 meters 30 Example 2 hours 30 minutes = ______ minutes To find the total amount of seconds, convert the hours into minutes. 2 x 60 = 120. Then add the amount of minutes to the total. 120 + 30 = 150. There are 150 minutes total. 31 Examples: Try these on your own!.
