BTU to Tons

60,000 BTU to Tons

60,000 BTU per hour equals 5 refrigeration tons. That's a 5 ton AC size.

Find it on the AC's label or spec sheet.

Cooling capacity

Your 60,000 BTU AC is a 5 ton AC.

5tons

Sold as a 5 ton AC. Exact: 5 tons.

1 ton = the cooling of melting 2,000 lb of ice per day.
Cooling kW
17.5843

1 refrigeration ton = 12,000 BTU/hr. Cooling kW is cooling capacity, not electricity use.

  • Tons = BTU/hr ÷ 12,000
  • Cooling kW = BTU/hr × 0.2930710702 ÷ 1,000

How the conversion works

Divide 60,000 by 12,000 to convert the capacity.

60,000 ÷ 12,000 = 5 tons

Cooling capacity: 17.5843 cooling kW. Cooling kW is not the electricity the AC uses.

Does 5 tons mean it fits my space?

A refrigeration ton is a capacity unit, equal to 12,000 BTU/hr; it is not the unit's weight.

There is no universal area-to-tonnage ratio. Room conditions, building design and climate affect the required capacity.

Whole-home systems require a separate load calculation.
