1. What is a Wattage to BTU Calculator?

Definition: This calculator converts electrical power in watts to thermal energy in British Thermal Units per hour (BTU/h).

Purpose: It helps in comparing electrical appliances with heating/cooling systems rated in BTUs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Thermal energy (BTU/h)
• \( P \) — Electrical power (Watts)

Explanation: The conversion factor 3.412 represents the number of BTUs produced per hour by one watt of electrical power.

3. Importance of Wattage to BTU Conversion

Details: This conversion is essential for sizing HVAC systems, comparing heating devices, and ensuring proper energy efficiency in thermal systems.

4. Using the Calculator

Tips: Simply enter the wattage value (must be > 0) and the calculator will instantly show the equivalent BTU/h.

5. Frequently Asked Questions (FAQ)

Q1: Why 3.412 as the conversion factor?
A: This is the exact conversion factor where 1 Watt = 3.412 BTU/h, based on the International Table calorie definition.

Q2: Does this work for both heating and cooling?
A: Yes, the conversion is the same for both heating and cooling applications.

Q3: How accurate is this conversion?
A: The conversion is mathematically exact, but real-world efficiency may vary based on device performance.

Q4: Can I convert BTU back to Watts?
A: Yes, divide BTU/h by 3.412 to get Watts.

Q5: Does this account for power factor?
A: No, this is a direct power conversion. For reactive power, additional calculations would be needed.
