BTU to Watts Conversion Formula

To convert BTU to watts, use this standard formula:

Watts = BTU × 0.293071

This formula works for BTU per hour (BTU/h) conversions.

Step-by-Step Calculation Example

Example: Convert 5000 BTU to watts

Step 1: Write the formula:
Watts = BTU × 0.293071

Step 2: Insert the value:
Watts = 5000 × 0.293071

Step 3: Perform the calculation:
Watts = 1465.355 W

Step 4: Final Answer:
5000 BTU = 1465.36 watts (rounded)
