BTU to Watts Conversion:
From: | To: |
The BTU (British Thermal Unit) to Watts conversion is used to translate power measurements between the imperial system (BTU/hr) and the metric system (Watts). This is particularly important in heating, ventilation, and air conditioning (HVAC) systems.
The calculator uses the conversion 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 power unit conversion is essential when working with equipment specifications, energy efficiency calculations, and comparing systems that use different measurement units.
Tips: Enter the BTU per hour value (must be greater than 0). The calculator will automatically compute the equivalent power in watts.
Q1: Why is the conversion factor 3.412142?
A: This exact value comes from the definition of 1 BTU as 1055.05585262 joules and 1 watt as 1 joule per second.
Q2: Can I convert watts back to BTU/hr?
A: Yes, multiply watts by 3.412142 to get BTU/hr (Q = W × 3.412142).
Q3: Is this conversion applicable to all power measurements?
A: Yes, this conversion applies to any power measurement, whether for electrical, mechanical, or thermal power.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact when using the precise factor of 3.412142.
Q5: When would I need to make this conversion?
A: Common applications include comparing air conditioner capacities (often rated in BTU/hr) with electrical power requirements (in watts).
