1. METRIC MEASUREMENT UNITS

2. METRIC UNITS OF LINEAR MEASURE
Based on powers of 10
Most frequently used units of length:
kilometer
meter
centimeter
millimeter

3. METRIC LINEAR UNITS
The following list shows several units of linear measure and their lengths in meters:
1 kilometer (km) = meters (m)
1 hectometer (hm) = meters (m)
1 dekameter (dam) = meters (m)
1 meter (m) = meter (m)
1 decimeter (dm) = meter (m)
1 centimeter (cm) = meter (m)
1 millimeter (mm) = meter (m)
There are a lot of these conversions on your conversion sheet with the back covering the prefixes and some of the conversions covered on the front. In metric, the unit is not as important as the prefix.

4. CONVERTING METRIC LENGTHS
Express 75 decimeters as meters
Express 1.95 centimeters as millimeters
**Notice I converted to meters and back to millimeters. This is not required, you can slide the decimals but most non-metric using people have trouble sliding the decimal. Especially when we get to other dimensions. The conversions used above are on your conversion sheet and keep you from sliding the wrong direction.

5. METRIC AREA CONVERSIONS
Express 84.5 square centimeters as square decimeters
These conversions are not all on your sheet but to go from first to second dimension you are squaring measurements from the first….so 10dm in a meter in linear (first) so 100dm2 = 1m2
Express 5.6 square hectometers as square Dekameters
Capital D to show Deka instead of deci
Dam is also used for Dekameters

6. METRIC VOLUME UNITS
Express 38,500 cubic millimeters as cubic decimeters
Convert 2.5 km3 as cm3 (also called cc)

7. METRIC UNITS Commonly used capacity-cubic measure equivalents:
1 milliliter (mL) = 1cubic centimeter (cm3)
1 liter (L) = 1cubic decimeter (cm3)
1 liter (L) = cubic centimeters (cm3)
1000 liters (L) = 1 cubic meter (m3)
Commonly used weight (mass) measure equivalents:
1000 milligrams (mg) = 1gram (g)
1000 grams (g) = 1kilogram (kg)
1000 kilograms (kg) = 1 metric ton (t)

8. COMPOUND UNITS Kilometers per hour can be written:
Products or quotients of two different units
Converted to smaller or larger equivalent compound unit measures using unity fractions
Expressed using per such as kilometers per hour which indicates division
Kilometers per hour can be written:

9. COMPOUND UNIT EQUIVALENTS
Simple needs only one unit to be converted
Complex needs more than one unit to be converted
Express kilometers per hour as meters per minute

10. Extremely large and small measures
Top and bottom of chart on conversion sheet
Tera, Giga, Mega are very large (heard in computer world and astrology)
micro, nano, pico are very small (heard in biology)
They work the same in unity fraction method just more conversions. With these you will use scientific notation in most cases.
It is 2.4x1020 m to the sun. How far is that in Terameters?
A cell is 5.7 micrometers thick. How many picometers is that?

11. METRIC-CUSTOMARY CONVERSIONS
Length
1 in = cm
1 ft = cm
1 yd = m
1 mi = km
Weight
1 oz = g
1 lb = kg
1 (short) ton = kg
Volume
1 cu in. (in3) = cm3
1 fl oz = cm3
1 tsp = mL
1 tbsp = mL
1 qt = L
1 gal = L

12. EXAMPLES Convert 8.24 in to millimeters
Convert 9.25 ft2 to square centimeters

13. PRACTICE PROBLEMS Express 63 meters as centimeters
