Can you convert a propane bbq to a natural gas bbq?

Natural gas and propane are crompressed at different pressures so the require differnt orifices for burners to meter the gas. There are some logistical problems, natural gas tanks are much bulkier than propane and are much less convenient to refill and weigh more for equal volume, this is the reason campers run on propane. Also, hooking to your house gas if you were able to change the orifice would seem dangerous, most CNG things in your house are effectively permanent (water heater, stove, dryer) they arent outside and the dont move. Could you convert it? Yes. Would it be worth the time, effort, and risk? No
