Conversion Factor = 300cm Multiply every number on top of the fence and divide by the bottom. 1516 g 1 kg 1000 g conversion factor 1.516 kg Convert 1200 cm to m. Convert 5200 mL to L. Convert 3 km to mm. Common Conversion Factors 5280 ft = 1 mile 12 in = 1 ft 1 mile = 1600 m 1 in = 2.54 cm 3 ft = 1 yard English to Metric conversion factors 1. Convert 45 m/s to miles/hr. 2. Convert 8 km/min to m/s.
