## Grow Room BTU Calculator

### Calculation Formula

The formula to calculate BTUs from wattage, quantity, and efficiency is:

\[ BTUs = \sum \left( \frac{Wattage \times Quantity \times 3.41}{Efficiency} \right) \]

Where:

- \(BTUs\) is the British Thermal Units produced.
- \(Wattage\) is the power consumption in watts.
- \(Quantity\) is the number of units.
- \(Efficiency\) is the efficiency factor (default is 0.92).
- 3.41 is the conversion factor from watts to BTUs.
