HVAC Capacity kW / BTU·h⁻¹ / Refrigeration Ton Converter
Convert cooling/heating capacity between kilowatts, BTU per hour and refrigeration tons for equipment comparison and preliminary engineering communication.
Results
Engineering method
Uses fixed unit conversion factors. This converts rated capacity units only and does not calculate building loads, seasonal efficiency or code compliance.
1 refrigeration ton = 12,000 BTU/h ≈ 3.51685284 kW.
