Conversion Ton to Btu per hour. The ton (ton of refrigeration) is a unit of power. This tool converts tons to btu per hour (ton to btu/h) and vice versa. 1 ton = 12000 btu per hour. The user must fill one of the two fields and the conversion will become automatically.
Energy consumption and output is measured in British Thermal Units regardless of energy source. BTUs are convenient because each energy is measured differently: LP gases are measured in gallons, natural gas is measured in cubic feet, electricity is measured in kWh, etc.The same goes for price (dollars per gallon, per thousand cubic feet, per kWh).his is easily converted into gallons: one only needs to divide the number of BTUs by 91,574 (number of BTUs per gallon), so a 200,000 BTU/hr furnace will use around 2.2 gallons of propane each hour it is running (this seems like a lot and is only true if the appliance is running at full power all the time).
