1. What is BTU/hr?

BTU/hr (British Thermal Units per hour) is a unit of power commonly used in heating and cooling systems. One BTU represents the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit.

2. Conversion Formula

The conversion formula from watts to BTU/hr is:

Where:

• 1 Watt = 3.412142 BTU/hr
• 1000 Watts = 3412.142 BTU/hr

3. Practical Applications

Details: This conversion is essential for comparing electrical power (watts) with thermal power (BTU/hr), commonly needed when sizing air conditioners, heaters, or other HVAC equipment.

4. Using the Calculator

Tips: Enter the power in watts to get the equivalent in BTU/hr. The default value shows the conversion for 1000 watts.

5. Frequently Asked Questions (FAQ)

Q1: Why convert watts to BTU/hr?
A: Many heating/cooling systems are rated in BTU/hr while electrical systems use watts, making conversions necessary for system compatibility.

Q2: How accurate is this conversion?
A: The conversion factor (3.412142) is exact, so calculations are mathematically precise.

Q3: What's the BTU/hr equivalent of common wattages?
A: 500W = 1706 BTU/hr, 1500W = 5118 BTU/hr, 2000W = 6824 BTU/hr.

Q4: Does this account for efficiency?
A: No, this is a direct unit conversion. Actual thermal output depends on device efficiency.

Q5: Can I convert BTU/hr back to watts?
A: Yes, divide BTU/hr by 3.412142 to get watts.
