Working on the Railroad  Step 1:  What to what?  Step 2:  Write conversion factor(s)  Step 3:  Train tracks

Volume - Liters << 1 mL1 kL1 L

Mass - Grams << 1 mg1 kg1 g.

Length - Meters << 1 mm 1 km 1 m.

Review Key Points  A conversion factor shows the same value with two different units.  Dimensional analysis is a tool used to convert from one unit to another.

Working on the Railroad  Step 1:  What to what?  Step 2:  Write conversion factor(s)  Step 3:  Train tracks

Practice! 1-Step Problems  How many meters are in 10 centimeters?  How many centimeters are in 327 meters?

Practice! On your own!  The distance from New Orleans to Miami is 1387 kilometers (862 miles). Convert 1387 kilometers to meters!

Worksheet Time  Complete the front and 1-5 on the back
