Key Terms

Metric units

System of measurementbased on units of a meter (meter, gram, liter, etc…)

Non metric units derivedfrom local units overCenturies (inches, feet,pounds, ounces, etc…)

Conversion=ProportionConversionfactor!

What are you trying tofind?

Set up a proportion-keeping units aligned!

Cross multiply and divide to find x!

Ex) 10 mm = 1 cm

How many millimeters are in 5.2 centimeters?

10 mm = x mm1 cm 5.2 cm

10 ( 5.2) = 1 x

Metric-Let’s convert!

1) If there are 10 millimeters in a centimeter, how many millimeters make up 12 centimeters?

2) If there are 100 centimeters in a meter, how many centimeters are in 2.5 meters?

3) If there are 1000 meters in a kilometer, how many kilometers equals 3500 meters?

Practice1) If 1 cm on a map of

Chicago = 1 km in real distance, how many meters would be represented by 5 cm on my map?

2) If 10 mm on a map of Harlan = 100 m in real distance, what would the distance be in cm of 60 mm on the map?

3) 4.2 cm = dm4) mm

= 100 m5) 72 cm = m6) ¾ km = m7) cm = 10.5 mm8) 10 hm = dc

Practice

1) 4.2 cm = dm2) mm = 100 m3) 72 cm = m4) ¾ km = m5) cm = 10.5 mm6) 10 hm = dc

Exit Ticket-Sticky Note

How many decimeters are in 4.5 kilometers?
