Without looking could you tell me..
How many pounds does a cubic feet of water have?
How many BTUs do you need to heat 10x10x3 ft water pool 20 degrees F?
How much work in ft-lb is done by gravity when a 10 oz mass drops from 19 yards?
How many HP are needed to rais 2400 lbs 74 inches in 30 sec?
It is obvious you have 0 experience doing back-of-the-envelope calculations for scientific or engineering purposes. It is a no-contest between the metric and the imperial systems.
