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. How Does the Conversion Work?

The conversion from watts to BTU/hr uses the formula:

Where:

• 1 Watt = 3.412142 BTU/hr
• This conversion factor comes from the exact relationship between the two units

Example: 1500 watts × 3.412142 = 5118.21 BTU/hr

3. Practical Applications

Details: This conversion is particularly useful for sizing air conditioners, heaters, and other HVAC equipment where power ratings may be given in different units.

4. Using the Calculator

Tips: Enter the wattage you want to convert. The calculator will automatically compute the equivalent BTU/hr value. Default value is set to 1500 watts.
