The formula to calculate Lux from PPFD (\(\mu mol m^{-2} s^{-1}\)) is:

\[ Lux = PPFD \times Conversion\ Factor \]

Where:

- \(Lux\) is the illuminance in lux.
- \(PPFD\) is the Photosynthetic Photon Flux Density.
- Conversion Factor depends on the type of light source.

PPFD (Photosynthetic Photon Flux Density) is a measure of the number of photons in the photosynthetically active radiation (PAR) range that are incident on a surface every second.

Lux is a measure of illuminance, the total amount of visible light illuminating a point on a surface.

Let's assume the following values:

- PPFD = 100
- Light Type = Sunlight

Using the formula:

\[ Lux = 100 \times 54 \]

Evaluating:

\[ Lux = 5400 \]

The Lux is 5400.
