BTU to Ton Conversion Formula:
| From: | To: |
The BTU to ton conversion is used in refrigeration and air conditioning to convert British Thermal Units per hour (BTU/h) to tons of refrigeration. One ton of refrigeration equals 12,000 BTU per hour, which represents the cooling capacity needed to melt one ton of ice in 24 hours.
The calculator uses the conversion formula:
Where:
Explanation: This conversion is essential for sizing air conditioning and refrigeration systems, as tons are the standard unit for measuring cooling capacity in HVAC applications.
Details: Accurate conversion between BTU and tons is crucial for proper HVAC system sizing, energy efficiency calculations, equipment selection, and ensuring adequate cooling capacity for residential, commercial, and industrial applications.
Tips: Enter the BTU value in the input field. The calculator will automatically convert it to tons of refrigeration. For 22,000 BTU, the result is approximately 1.8333 tons.
Q1: Why is 1 ton equal to 12,000 BTU?
A: This originates from the amount of heat required to melt one ton (2,000 pounds) of ice in 24 hours, which equals 288,000 BTU over 24 hours, or 12,000 BTU per hour.
Q2: What is the typical tonnage for residential AC units?
A: Residential units typically range from 1.5 to 5 tons, with 2-3 tons being common for average-sized homes.
Q3: How many BTU is a 1.5 ton AC unit?
A: A 1.5 ton AC unit has a cooling capacity of 18,000 BTU (1.5 × 12,000 = 18,000).
Q4: Is this conversion used worldwide?
A: While tons are commonly used in North America, other regions may use kilowatts (kW) as the standard unit for cooling capacity.
Q5: How accurate is this conversion for system sizing?
A: This provides a basic conversion, but professional HVAC sizing requires detailed calculations considering insulation, climate, room size, and other factors.
