1. What is a BTU Calculator from Watts?

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

Purpose: It helps in HVAC, electrical, and energy calculations where power measurements need to be converted between different units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — BTU per hour (BTU/h)
• \( P \) — Power in watts (W)

Explanation: 1 watt is equal to 3.412 BTU per hour. This conversion factor is derived from the relationship between the two units of power measurement.

3. Importance of BTU Calculation

Details: Accurate BTU calculations are essential for proper sizing of heating and cooling systems, energy efficiency assessments, and electrical system design.

4. Using the Calculator

Tips: Simply enter the power in watts and the calculator will automatically compute the equivalent BTU/h value.

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 equals 3.41214 BTU per hour (exact conversion factor).

Q2: What's the difference between BTU and BTU/h?
A: BTU measures energy, while BTU/h measures power (energy per unit time).

Q3: When would I need this conversion?
A: Common uses include sizing air conditioners, comparing heating systems, or converting electrical power to thermal output.

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

Q5: Is this conversion affected by temperature?
A: No, the conversion factor is constant regardless of temperature.
