BTU Conversion Formula:
From: | To: |
Definition: This calculator converts electric power in watts to British Thermal Units per hour (BTU/h).
Purpose: It helps in understanding the heat output equivalent of electrical devices and systems.
The calculator uses the formula:
Where:
Explanation: The conversion factor 3412 represents the number of BTUs per hour equivalent to 1 watt of electrical power.
Details: This conversion is essential for HVAC sizing, electrical system design, and understanding heat generation from electrical equipment.
Tips: Simply enter the electric power in watts. The value must be > 0.
Q1: Why is the conversion factor 3412?
A: 1 watt equals 3.412 BTU/h, so the conversion uses this exact relationship multiplied by 1000.
Q2: What's a typical wattage for household appliances?
A: A space heater might be 1500W (≈ 5118 BTU/h), while a computer might be 300W (≈ 1024 BTU/h).
Q3: Does this account for efficiency losses?
A: No, this shows the theoretical maximum heat output. Actual heat may be less depending on device efficiency.
Q4: Can I convert BTU/h back to watts?
A: Yes, divide BTU/h by 3.412 to get watts.
Q5: Why measure heat in BTU/h?
A: BTU/h is a common unit for heating and cooling capacity in many countries, especially for HVAC systems.
