On the Flow Rate by Volume page, cubic inches is needed. It should be supported for all the same time units as cubic feet. The displacement of many piston engines is measured in cubic inches. To calculate the flow rate of air (or fuel air mixture) through an engine at a given rpm one must multiply the displacement by the rpm, yielding flow rate per minute. Currently one must multiply or divide by 144 and use cubic feet.

Thank you for the suggestion. We'll add cubic inches in our next update.
