Aircraft; Human Factors
During a flight from ZZZ; I experienced an inflight stoppage of the aircraft engine. During my preflight; I calculated the fuel usage to be 6 GPH. In addition to my normal prefight; I ensured I had enough fuel in the airplane for the intended flight; which amounted to 19 gallons between the two tanks. The 19 gallons; according to my performance calculations and passed experience; should have allowed for a 3-hour flight. My prefight calculations indicated I would have a flight time between 1 hour and 40 minutes in the best conditions; and 2 hours and 10 minutes in the worst conditions. After a flight of 1 hour 50 minutes; the engine began to die. After initial power loss; I ran through the normal engine failure procedures. With an unsuccessful engine start procedure and the airport not in view; I landed in the best suitable field. The landing was successful minimal damage to property and no injury to persons on the ground.
C150 pilot reported an inflight loss of engine power due to fuel mismanagement; resulting in a forced off-airport emergency landing.
