1. What is a Watts to BTU Calculator?

Definition: This calculator converts power measurements from watts to British Thermal Units per hour (BTU/h).

Purpose: It helps in comparing electrical power (watts) with thermal energy (BTU), commonly used in HVAC, appliances, and energy calculations.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{BTU/h} = \text{Watts} \times 3.412 \]

Where:

Explanation: This conversion factor comes from the exact relationship where 1 watt equals 3.412142 BTU per hour.

3. Importance of Watts to BTU Conversion

Details: Converting between these units is essential when comparing electrical devices with heating/cooling systems that use BTU ratings.

4. Using the Calculator

Tips: Simply enter the wattage value you want to convert. The calculator will instantly show the equivalent BTU/h value.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3.412?
A: This exact value comes from the definition of BTU and watt: 1 BTU = 1055.06 joules and 1 watt = 1 joule/second.

Q2: Can I convert BTU back to watts?
A: Yes, divide BTU by 3.412 to get watts. We may add a BTU to watts calculator in the future.

Q3: Is this BTU/h or just BTU?
A: The result is BTU per hour (BTU/h) since watts are a rate of energy per second.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact, though real-world efficiency factors may affect actual thermal output.

Q5: What's a typical conversion example?
A: A 1500W space heater produces about 5,118 BTU/h (1500 × 3.412).
