1 Patterns in Measurement Systems Converting in and between the Metric and Customary Systems

2 The Customary System

3 12 in = 1 ft 3 ft = 1 yd 1760 yd = 1 mi inftmiyd × 1760× 3× 12 ÷ 12÷ 3÷ 1760 Length

4 8 fl oz = 1 c 2 c = 1 pt 2 pt = 1 qt fl ozcqtpt × 2 × 8 ÷ 8÷ 2 Capacity 4 qt = 1 gal gal × 4 ÷ 4

5 16 oz = 1 lb 2000 lb = 1 T ozlbT × 2000× 16 ÷ 16÷ 2000 Weight

10 Conversion Shortcut. Write this down! kmmmcmm × 1,000 × 100× 10 ÷ 1,000÷ 100÷ 10

11 kilo- hecto- deka- unit deci- centi- milli- move the decimal to the right as you go down. move the decimal to the left as you go up.

12 Conversions If you go up on the chart the decimal will go to the left. If you go down on the chart the decimal will go to the right.
