BTU to Tons

6,000 BTU to Tons

6,000 BTU per hour equals 0.5 refrigeration tons. That's a 0.5 ton AC size.

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

Cooling capacity

Your 6,000 BTU AC is a 0.5 ton AC.

0.5tons

Sold as a 0.5 ton AC. Exact: 0.5 tons.

1 ton = the cooling of melting 2,000 lb of ice per day.
Cooling kW
1.7584

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 6,000 by 12,000 to convert the capacity.

6,000 ÷ 12,000 = 0.5 tons

Cooling capacity: 1.7584 cooling kW. Cooling kW is not the electricity the AC uses.

Does 0.5 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.
