1. What is Watts to BTU Conversion?

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

Purpose: It helps determine the heat output of electrical devices like heaters, appliances, and HVAC systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Heat output (BTU/h)
• \( P \) — Electrical power (Watts)
• 3.412 — Conversion factor (BTU/h per Watt)

Explanation: 1 Watt of electrical power produces approximately 3.412 BTU of heat per hour.

3. Importance of Watts to BTU Conversion

Details: This conversion is essential for sizing heating equipment, calculating cooling loads, and comparing electrical and thermal energy outputs.

4. Using the Calculator

Tips: Enter the power in watts. The calculator will automatically compute the equivalent heat output in BTU/h.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3.412?
A: This comes from the definition of BTU and Watt: 1 Watt = 3.412 BTU/h exactly.

Q2: Does this conversion work for all electrical devices?
A: Yes, but remember that not all electrical energy is converted to heat (some becomes light or motion).

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

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

Q5: What's a typical wattage for household appliances?
A: Space heaters: 1500W, Computers: 300-800W, Light bulbs: 5-100W (LEDs use less).
