Name METRIC CONVERSIONS Hour Sometimes you need to change meters to centimeters, or kilometers to meters. Here is an easy way to do that: Here are the metric units of length written from largest to smallest. km hm dam m dm cm EXAMPLE: To convert meters (m) to millimeters (mm) you start at m and move to the right. Count the number of jumps you make to get to mm. 1 jump 2 jumps 3 jumps km hm dam m dm cm mm Since you moved 3 jumps to the right, move the decimal point 3 places to the right. (If you run out of numbers, add a zero for each jump you make after the last number.) 2.05 = 2050 2.05m = 2050mm 123 Problems: Fill in each blank for the problems below. 1. 410 cm = 3. 5. 7. 9. 11. 13. 15. 17. 19. 35 ml = 12 km = 3.4 kg = 157m= 13.5 mm = .69 km = 2500 ml = 27 mg= .135 km = mm g L km g cm cm mm L m mm 2. 4. 6. 8. 10. 12. 14. 16. 18. 20. 16700 m 455 L= .00005 km = 3.57 cm = 157 kg = 15.2 km = 1m= 1000 m .09 cm 107 m = 1 of 1 mm ml m m g cm cm km km Dimensional Analysis review 1.
