## Hps Grow Light Btu Calculator

### Calculation Formula

The formula to calculate BTUs from wattage and efficiency is:

\[ BTUs = \frac{Wattage \times 3.41}{Efficiency} \]

Where:

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