1
Metric System I can convert between units in the metric system Sunday, October 18, 2015

2
Why do scientists use metric units? Easy to use Based on the decimal system (each unit is 10 times larger than the next) Precise/Accurate measurements smaller than an inch so you don’t have to use fractions No memorization of conversion facts e.g. 1 mile= 5,280 feet Globally used so no conversion is needed from one country to the next

3
What are the metric measurements that we are learning about? Meter Length Liter Volume: how much space something occupies or takes up Gram Weight or Mass: measure of the amount of matter in an object….an object’s mass never changes!

4
How to remember different lengths in the metric system: When you think of a millimeter (mm) think of: The thickness of a dime. When you think of a centimeter (cm) think of: The width of your pinky.

5
Guidelines to using metrics 7 basic units or stair steps King Henry Died Monday Drinking Chocolate Milk. Kilo K 1000 Hecto H 100 Deka Da 10 Meter, gram, or liter m, g, L 1 Deci D.1 Centi C.01 Milli M.001

6
How to remember different lengths in the metric system: When you think of a meter (m) think of: The height of the doorknob. When you think of a kilometer (km) think of: A little more than half of a mile

7
How to understand the ruler: One side has inches (duh!) The other side is the metric side. The big numbers represent centimeters The smaller lines represent millimeters. How many millimeters are in a centimeter? 10

8
With the group you will be put into, use a meter stick to measure the items on your chart. Be sure to measure in meters, centimeters, and millimeters.

9
How to remember different volumes in the metric system: When you think of a liter (L) think of: About the size of a bottle of water. When you think of 5 milliliters (mL) think of: One teaspoon When you think of 2 kiloliters (kL) think of: A hot tub

10
How to remember different masses in the metric system: When you think of a gram (g) think of: A paper clip When you think of a kilogram (kg) think of: A little more than 2 pounds.

11
Measurement Conversions to Know: 1 m = 100 cm 1 cm = 10 mm 1 m = 1,000 mm 1 km = 1,000 m 1 g = 100 cg 1 cg = 10 mg 1 g = 1,000 mg 1 kg = 1,000 g 1 L = 100 cL 1 cL = 10 mL 1 L = 1,000 mL 1 kL = 1,000 mL

12
What is the order of the metric system? King Henry Died by Drinking Chocolate Milk King: Kilo Henry: Hecto Died: Deca By: Base (m, L, g) Drinking: Deci Chocolate: Centi Milk: Milli

13
How to convert within the metric system: Example 1: to convert 3 meters into decimeters, multiply 3 by 10 one time. 3 m = 3* 10 dm = 30 dm Example 2: to convert 7 hectoliters into milliliters, multiply 7 by 10 five times. 7 hL = 7 * 10 * 10 * 10 * 10 * 10 mL = 700,000 mL

14
Now you try: 7 km = __________ m 6 g = __________ cg 9.15 kL = __________ L 6.25 kg = __________ mg 14.2 m = __________ cm

15
How to convert within the metric system: Example 3: to convert 6 grams into kilograms, divide 6 by 10 three times. 6 g = 6 ÷ 10 ÷ 10 ÷ 10 kg = 0.006 kg Example 2: to convert 17 millimeters into centimeters, divide 17 by 10 one time. 17 mm = 17 ÷ 10 cm = 1.7 cm

16
Now you try: 14 mL = __________ L 3.97 g = __________ kg 915 L = __________ kL 45 mg = __________ dag 10 m = __________ dam

17
