Ton To Watt Conversion Formula:
| From: | To: |
The ton to watt conversion is used to convert refrigeration tons (a unit of cooling power) to watts (the standard SI unit of power). One ton of refrigeration equals 3516.85 watts, which represents the amount of power needed to melt one ton of ice in 24 hours.
The calculator uses the conversion formula:
Where:
Explanation: This conversion factor (3516.85) is derived from the definition of a ton of refrigeration as the amount of power required to melt one ton (2000 pounds) of ice at 32°F in 24 hours.
Details: Accurate power conversion is essential for HVAC system design, energy efficiency calculations, equipment sizing, and comparing cooling capacities across different measurement systems.
Tips: Enter the refrigeration ton value in the input field. The value must be a positive number. The calculator will automatically convert it to watts using the standard conversion factor.
Q1: Why is the conversion factor 3516.85?
A: This value comes from the definition that one ton of refrigeration equals the heat absorption of melting one ton of ice in 24 hours, which is 12,000 BTU/h, and 1 BTU/h equals approximately 0.293071 W.
Q2: Is this conversion used worldwide?
A: While the ton of refrigeration is primarily used in North America, the conversion to watts is important for international engineering projects and equipment specifications.
Q3: What are typical tonnage values for residential AC units?
A: Residential air conditioners typically range from 1.5 to 5 tons, with each ton representing about 12,000 BTU/h of cooling capacity.
Q4: How accurate is this conversion?
A: The conversion factor 3516.85 is a standardized value accepted in the HVAC industry and provides precise conversion between these units.
Q5: Can this calculator be used for heating systems too?
A: While the ton is specifically a cooling measurement, the conversion to watts can be useful for comparing different types of heating and cooling systems using a common unit.
