I'll start. 12 square feet = 1 Horsepower I don't get it. energy is measured in units whose dimensions must be mass times length squared divided by time squared. square feet is a measure of area, and horsepower is a measure of power, not energy. Power is energy divided by time. 2 Quote Share this post Link to post Share on other sites

I had two separate problems with your formula: 1) neither area nor power is a measure of energy, and 2) the "equation" fails a dimensional analysis. If your "equation" is A = P, then you need a conversion factor F that you did not supply and that has dimensions of mass divided by time. A x F = P. The factor F must be hp/12 sq.ft.

Like I said it is a weird measure of energy (or power). Quote Share this post Link to post Share on other sites
