The BTU (British Thermal Unit) to Watts conversion is used to translate power measurements between the imperial and metric systems. This is particularly important in heating, cooling, and energy applications where different systems use different units of measurement.
The conversion uses the following formula:
Where:
Explanation: The conversion factor comes from the exact relationship between the two units, where 1 watt equals approximately 3.412142 BTU per hour.
Details: Accurate unit conversion is essential when working with equipment specifications, energy calculations, or comparing systems that use different measurement standards.
Tips: Enter the BTU/hr value you want to convert. The value must be positive. The converter will automatically calculate the equivalent power in watts.
Q1: Why is the conversion factor 3.412142?
A: This exact value comes from the definition of BTU and watt: 1 BTU/hr = 0.29307107 watts, so the inverse is 1 W = 3.412142 BTU/hr.
Q2: What are common applications for this conversion?
A: HVAC system specifications, heater ratings, air conditioner capacities, and energy efficiency calculations often require this conversion.
Q3: Can I convert watts back to BTU/hr?
A: Yes, simply multiply watts by 3.412142 to get BTU/hr.
Q4: Is this conversion exact?
A: Yes, the conversion factor is based on exact definitions, not approximations.
Q5: Are there different types of BTU?
A: In most practical applications, we use the International Table BTU (IT BTU), which is what this converter uses.
