Tons to BTU/hr conversion calculator How to convert BTU/hr to tons. One refrigeration ton is equal to 12000 BTUs per hour: 1 RT = 12000 BTU/hr. One BTU per hour is equal to 8.33333×10-5 refrigeration ton: 1 BTU/hr = 8.33333×10-5 RT . So the power P in refrigeration tons (RT) is equal to the power P in BTUs per hour (BTU/hr) divided by 12000:
Boiler load - The horsepower, lbs of steam per hour, or BTU is the rating indicating the maximum capacity of a boiler.

· A 4'' x 6'' x 12'' tank with 1800 gallons of water needs to be heated from 60°F to 95°F in 3 hours. The tank has R-4 insulation and the minimum ambient temperature is 0°F. To begin we need to convert the gallons of water to pounds: lbs = G x D1. G = gallons. D1 = lbs per gallon from the chart below. lbs = 1800 x 8.34. lbs = 15,012
Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)
Air conditioners are rated in Tons capacity instead of kW or kVA rating because Air conditioners are designed on the basis of quantity of heat removal from room, hall or specific area.
