**Conversion Practice Try these conversions using the ladder method.**

1000 mg = __1.0___ g 1 L = _1000__ mL 160 cm = 1600 mm 14 km = __14000 m 109 g = .109 kg 250 m = .250 km Compare using <, >, or =. 56 cm < m 7 g > mg

**Metric Conversion Challenge**

Write the correct abbreviation for each metric unit. 1) Kilogram __kg 4) Milliliter __mL_ 7) Kilometer __km 2) Meter __m_ 5) Millimeter __mm 8) Centimeter __cm 3) Gram ___g__ 6) Liter __L__ 9) Milligram __mg Try these conversions, using the ladder method. 10) 2000 mg = __2__ g 15) 5 L = __5000_ mL 20) 16 cm = __160___ mm 11) 104 km = __104000_ m 16) 198 g = .198____ kg 21) 2500 m = __2.5__ km 12) 480 cm = _4.80__ m 17) 75 mL = _.075__ L 22) 65 g = _65000_ mg 13) 5.6 kg = 5600__ g 18) 50 cm = _.50__ m 23) 6.3 cm = _63_ mm 14) 8 mm = __0.8_ cm 19) 5.6 m = __560_ cm 24) 120 mg = _.120__ g
