Forklift cylinders typically hold between 20 and 33 pounds of propane. To convert this to gallons, we need to know the density of propane. The density of propane is approximately 4.2 pounds per gallon.
Therefore, a 20-pound propane cylinder will hold approximately 20 / 4.2 = 4.76 gallons of propane. A 33-pound propane cylinder will hold approximately 33 / 4.2 = 7.86 gallons of propane.
