Metric Stairs How to do Metric Conversions

3
Metric System System of measurement. Designed to be easy to use and universal. (built on powers of ten) Correct name is the “International System of Units”( or SI for short).

4
Built on a Root Each property of matter has a root word that is the base measurement for that property. For example: Grams (g) are for mass Liters (L) are for volume Meters (m) are for distance

5
Add a Prefix To change the value of the root (make it bigger or smaller), you add a prefix Smaller Milli (m) – 1/1000 of the root (1000 times smaller) Centi (c) – 1/100 of the root (100 times smaller) Deci (d) – 1/10 of the root (10 times smaller) Bigger Deka (dk) – 10 times bigger than root Hecto (h) – 100 times bigger than root Kilo (k) – 1000 times bigger than root.

6
Easy Conversions kilo- hecto- deka- root deci- centi- milli- You can use this simple drawing to convert any metric measurement to another metric measurement. The stairs have 7 steps going down left to right

7
How does it work? kilo- hecto- deka- root deci- centi- milli- First, identify the prefixes you are being asked to convert between. Example: “Convert 2.345 cm into hectometers” cm is centimeters and change is to hectometers.

8
How does it Work? kilo- hecto- deka- root deci- centi- milli- Next draw out the stairs. Third, put a mark on the starting prefix (centi in our example problem)

9
How does it Work? kilo- hecto- deka- root deci- centi- milli- Fourth, “walk” up/down the stairs to the prefix you are converting to (hecto in our example) Count the number of steps you traveled and note direction as either left or right. 1 4 3 2 Left

10
How Does it Work Now go to the original number ( 2.345 ) and move the decimal point the same direction and number of “steps” as you did on the stairs. 2.345 4 spaces left 0.0002345 hm

11
Practice Convert 4.3 km to meters Convert 462 cg to hg Convert 1 mL to kL
