Mass Length Volume Temperature

Conversion factors Quantity needed = quantity given x conversion factor 5.712g in mg and kg 1g = 103 mg Conversion factor = 103mg/1g or 1g/103 mg Use the conversion factor with the same unit in the numerator 5.712g x 103mg/1g

Conversion factors cm  m kg  g mL  L g  μg kg  mg mm cm m  km
