2. Do Now The Great Wall of China runs for 5,500.3 miles. How long is this in feet? You’re supposed to drink 64 fl oz (8 glasses) of water everyday. How much is this in quarts? In gallons?

5. Converting Between Metric Units Multiply by the ratio of units (see conversion sheet) To convert between units, keep your old units diagonal to each other with the new units on top For example: Convert 450 centimeters to meters.

6. Practice Conversions Convert 450 centimeters to millimeters Convert 12 kilograms to grams Convert 200 centiliters to liters Convert 3 kilometers to centimeters
