GPH is meaningless unless you know how much distance you have covered. For instance, my boat burns about 15 to 16 GPH at 35 MPH and only 10 GPH at 20 MPH, but I can go futher on a gallon of gas at 35 MPH. I also burn about around .8 to 1 gallon per hour at idle, even if I'm not in gear. That yields 0 MPG. My fuel flow is measure by a device that also measures speed, it can display MPH, MPG or GPH.
