10-14 Mtoe Ð´ÐµÑÑ. It is approximately the energy needed to heat one pound of water by 1 degree Fahrenheit. A unit of volume; register ton. Example 4. BTU : The British thermal unit is a traditional measure unit of energy, approximately equals 1055 joules. RapidTables.com | This tool converts btu per hour to tons (btu/h to ton) and vice versa. Now, the British thermal unit is almost replaced by the SI unit of energy, the joule. If you find something unclear, you can ask about it in the comment section below. air), Sensible Heat (BTU/hr) = 1.1 x CFM x Δt (std. divide 40 by 0.0003928 to get 101,832.99 BTU/hour. Example: You have 4 tons device. Approximately 3504 Watts (SI). What is a BTU? Check the chart for more details.

For example, if you had one ton, you would divide 1 by 0.00008333 to get 12,000 BTU/hour. There for a 2 ton unit is a 24,000 BTU/h unit and a 3 ton unit is a 36,000 BTU/h unit. 30,000 BTUs is 2 1/2 tons. A unit of weight (mass) equal to 2240 pounds (a long ton) or 2000 pounds (a short ton) or 1000 kilograms (a metric ton).
