Enter the Lux and conversion factor into the calculator to determine the PPFD. This calculator can also evaluate any of the variables given the others are known.

## Lux To Ppfd Formula

The following formula is used to calculate PPFD from Lux.

PPFD = Lux * CF

Variables:

- PPFD is the Photosynthetic Photon Flux Density (μmol/m²/s)
- Lux is the total light intensity (Lux)
- CF is the conversion factor (0.0185 for sunlight, varies for different light sources)

To calculate the PPFD, multiply the Lux by the conversion factor. The conversion factor varies depending on the light source. For sunlight, the conversion factor is typically 0.0185. This formula provides a more accurate understanding of how much light plants are actually receiving for growth, as it measures only the light within the photosynthetically active radiation (PAR) range, which is light that plants can use for photosynthesis.

## What is a Lux To Ppfd?

Lux to PPFD (Photosynthetic Photon Flux Density) is a conversion that translates the measurement of total light intensity (Lux) into the measurement of the light intensity beneficial for plant growth (PPFD). Lux measures all visible light, regardless of its usefulness to plants, while PPFD measures only the light within the photosynthetically active radiation (PAR) range, which is light that plants can use for photosynthesis. Therefore, converting Lux to PPFD provides a more accurate understanding of how much light plants are actually receiving for growth.

## How to Calculate Lux To Ppfd?

The following steps outline how to calculate the Lux To PPFD using the formula: PPFD = Lux * CF.

- First, determine the Lux value.
- Next, determine the Conversion Factor (CF).
- Next, use the formula PPFD = Lux * CF to calculate the Photosynthetic Photon Flux Density (PPFD).
- Finally, calculate the Lux To PPFD.
- After inserting the Lux value and the Conversion Factor, calculate the PPFD using the formula above.
