1 decimeter is equal to 100 millimeters. In this case, 2 decimeters is equal to 200 millimeters. 1 hour is equal to 3600 seconds while 1 minute is equal to 60 seconds. In this case, 2 h 10 minutes is equal to 7800 seconds. 1 gram is equal to 1000 micrograms. Thus, 16 grams is equal to 16000 mg and 0.675 mg is equal to 0.000675 grams. 1 centimeter is equal to 10000 micrometers. Hence 462 micrometers is equal to 0.0462 centimetes. 35 meter per hour is equal to 0.009722 m/s
