About Watts (W) to BTU/hr Conversion

What are Watts and BTU/hr?

Watts (W) and British Thermal Units per hour (BTU/hr) are units used to measure power and heat energy rate, respectively:

• Watt (W): The SI unit of power, defined as one joule per second. It measures the rate of energy transfer.
• British Thermal Unit per hour (BTU/hr): A unit of heat energy transfer rate. One BTU is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

Formula for Watts to BTU/hr Conversion

The formula to convert watts to BTU/hr is:

\[BTU/hr = W \times 3.41214\]

Where:

• \(BTU/hr\) is the heat energy rate in British Thermal Units per hour
• \(W\) is the power in watts
• 3.41214 is the conversion factor (1 W ≈ 3.41214 BTU/hr)

Calculation Steps

1. Identify the power in watts.
2. Multiply this value by 3.41214 (since 1 W ≈ 3.41214 BTU/hr).
3. The result is the equivalent heat energy rate in BTU/hr.

Example

Let's convert 1000 watts to BTU/hr:

1. Given: \(W = 1000\)
2. Apply the formula: \(BTU/hr = 1000 \times 3.41214\)
3. Calculate: \(BTU/hr = 3412.14\)

Visual representation:

Therefore, 1000 watts is equivalent to approximately 3412.14 BTU/hr.
