1 Metric Conversions

2 What are Metric Conversions? Sometimes we need to change from one measurement to another. This is usually done because the unit that is used is either too big or too small for that type of measurement.

3 TOO BIG !!! 525,568 millimeters Sometimes the number is too big for the unit being measured.

4 Too Small km Sometimes the number is too small for the unit being measured

5 How Do We Fix This Problem? We can correct these problems by doing a process called Metric Conversion. When you do a Metric Conversion, you are changing from one unit of measurement to another.

6 So How Do I Do A Metric Conversion? We will be using a method called The Stair-step Method of Metric Conversion. It requires you to move the decimal in the number.

7 The Stair-step Kilo- Hecto- Deka- base units Deci- Centi- Milli- Grams, liters,meters King-Henry-Died-By-Drinking-Chocolate-Milk

8 The Stair-step : METER Km Hm Dam M Dm Cm Mm METERS King-Henry-Died-By-Drinking-Chocolate-Milk

9 How Do I Use This? -The first letter of the prefix in the unit of measurement tells you which step to start on. -The first letter in the second unit of measurement tells you which step to stop on. -Find which step to start on, and count the number of steps it takes to get to the step that you need to stop on. 5.0 Km_?_Hm

10 The Stair-step : METER Km Hm Dam M Dm Cm Mm METERS

11 How Do I Use This (cont.)? If you went to the right(downstairs) the decimal in the first measurement moves that many places to the right. If you went to the left (upstairs) then the decimal moves to the left. Fill any empty places with zeros. 5.0 Km_50_Hm

12 mm = ? m The decimal in mm moves three places to the left, becoming m km becomes 6.54 m km = ? m

13 1.45m  ___ cm

14 The Stair-step : METER Km- Hm Dam M Dm Cm Mm

15 4.0 mm  ___ dm

16 The Stair-step : METER Km- Hm Dam M Dm Cm Mm

17 0.022 hm  __dam

18 The Stair-step : METER Km- Hm Dam M Dm Cm Mm

19 0.108 km  ___ m

20 The Stair-step : METER Km Hm Dam M Dm Cm Mm

21 5 km  ___ mm , ,000,000
