Photons Per Watt Calculator

Formula

The formula to calculate the Photons Per Watt (PPW) is:

\[ PPW = \frac{P}{W} \]

Where:

Photons Per Watt (PPW): The number of photons emitted per watt of power.
Significance: Used in fields like photonics and lighting to measure the efficiency of light sources.

Let's say the total number of photons (P) is 1,000,000 and the total wattage (W) is 50 watts. Using the formula:

\[ PPW = \frac{1,000,000}{50} = 20,000 \]

So, the Photons Per Watt (PPW) is 20,000 photons/watt.
