Power Conversion Formula:
| From: | To: |
Watts to BTU/h conversion is a power unit conversion that translates electrical power (watts) to thermal power (British Thermal Units per hour). This conversion is essential in HVAC systems, electrical heating, and energy efficiency calculations.
The calculator uses the conversion formula:
Where:
Explanation: One watt of electrical power is equivalent to 3.41214 BTU per hour of thermal power, based on the International System of Units conversion standards.
Details: Accurate power conversion between watts and BTU/h is crucial for HVAC system design, electrical heating calculations, energy efficiency assessments, and comparing different types of heating and cooling systems.
Tips: Enter the power value in watts. The value must be positive and greater than zero. The calculator will automatically convert to BTU/h using the standard conversion factor.
Q1: Why is the conversion factor 3.41214?
A: This factor comes from the definition of BTU and watt. One BTU is approximately 1055 joules, and one watt is one joule per second, leading to this precise conversion factor.
Q2: What is the difference between BTU and BTU/h?
A: BTU is a unit of energy, while BTU/h is a unit of power (energy per unit time). BTU/h indicates how much thermal energy is produced or transferred per hour.
Q3: When is this conversion most commonly used?
A: This conversion is essential in HVAC industry for sizing air conditioners and heaters, in electrical heating applications, and for energy efficiency calculations in buildings.
Q4: Can I convert BTU/h back to watts?
A: Yes, to convert BTU/h back to watts, divide the BTU/h value by 3.41214 (W = BTU/h ÷ 3.41214).
Q5: Are there any limitations to this conversion?
A: This conversion assumes standard conditions and is a direct mathematical conversion. Actual performance may vary based on equipment efficiency and environmental factors.
