How To Work Out Cubic Metre Per Hour (m3/h)

Starting Unit Multiply By Divide By S.G = m3/h
lb per hour x 0.000454 ÷ Specific Gravity = Cubic Metre Per Hour
kilos per second x 3.6 ÷ Specific Gravity = Cubic Metre Per Hour
kilos per hour x 0.001 ÷ Specific Gravity = Cubic Metre Per Hour
metric tonnes per hour ÷ Specific Gravity = Cubic Metre Per Hour
litres per hour x 0.001 = Cubic Metre Per Hour
litres per minute x 0.06 = Cubic Metre Per Hour
litres per second x 3.6 = Cubic Metre Per Hour
imperial gallons per minute x 0.273 = Cubic Metre Per Hour
imperial gallons per hour x 0.00455 = Cubic Metre Per Hour
US gallons per minute x 0.227 = Cubic Metre Per Hour
US gallons per hour x 0.0038 = Cubic Metre Per Hour
