Was going to convert from propane to natty gas on dryer this year but found out today that the monthly rental on commercial meter is $750. If I need it two months I could have 2-2.5 cents a bushel just in meter rental. If I could keep the usage under 75,000 ccf's/month I can drop down to a medium commercial rate for $136/month. How many gallons of propane would equal 75,000 ccf's of natty gas? TIA
