A two-ton air conditioning system has a capacity of approximately how many BTU per hour?

Explanation:
Cooling capacity is measured in tons, with one ton equaling 12,000 BTU per hour. So a two-ton system provides 2 × 12,000 = 24,000 BTU per hour. That matches the standard definition and why a two-ton unit is described as about 24,000 BTU/hr. The other numbers correspond to different whole-ton equivalents (1 ton = 12,000 BTU/hr; 4 tons = 48,000 BTU/hr; 0.5 ton = 6,000 BTU/hr), which is why they don’t fit a two-ton capacity.
