BTU/hr to Watts Conversion Formula:
| From: | To: |
BTU/hr (British Thermal Units per hour) is a unit of power that measures heat output. It represents the amount of heat energy required to raise the temperature of one pound of water by one degree Fahrenheit in one hour.
The calculator uses the conversion formula:
Where:
Explanation: This conversion allows you to determine the heating capacity of electric radiators and other heating devices based on their electrical power consumption.
Details: Accurate BTU calculation is essential for proper heating system sizing, energy efficiency planning, and ensuring adequate heating capacity for different room sizes and insulation conditions.
Tips: Enter the wattage of your electric radiator or heating device. The value must be greater than 0. The calculator will instantly convert watts to BTU/hr for heat output assessment.
Q1: Why convert watts to BTU/hr for heating?
A: BTU/hr is the standard unit for measuring heating capacity, making it easier to compare different heating systems and determine appropriate sizing for rooms.
Q2: What is a typical BTU requirement for a room?
A: Generally, 20-25 BTU per square foot for moderate climates, 30-35 BTU for colder climates, and 35-40 BTU for very cold climates or poorly insulated spaces.
Q3: Can I use this for all electric heaters?
A: Yes, this conversion applies to all electric resistance heating devices including radiators, space heaters, and baseboard heaters.
Q4: How accurate is the 3.412 conversion factor?
A: The factor is exact for electric resistance heating where 100% of electrical energy is converted to heat energy.
Q5: Should I consider efficiency losses?
A: For electric resistance heating, efficiency is nearly 100%, so no additional factors are needed. For heat pumps, different calculations apply.
