METEOROLOGY – CONVERION & UNIT TOOL (METEOROLOGY) CALCULATOR
Lux To Wm2 Par
A precise tool.
What is the Lux To Wm2 Par & How does it work?
Illuminance (lux) is a unit of illuminance, defined as the amount of light falling on a surface per unit area. It is measured in lumens per square meter (lm/mΒ²). PAR stands for Photosynthetically Active Radiation, which is the spectral range of light that plants can use for photosynthesis.
1 text{ lux} = 0.00146 frac{mu mol}{m^2 s}
lux = illuminance in lumens per square meter
mu mol/m^2/s = Photosynthetically Active Radiation
mu mol/m^2/s = Photosynthetically Active Radiation
The conversion between lux and W/mΒ² (watts per square meter) is based on the luminous efficacy of a light source, which is typically around 683 lumens per watt for standard light sources. Therefore, 1 W/mΒ² β 683 lux.

Frequently Asked Questions
How do I convert lux to W/mΒ²?
To convert lux to W/mΒ², use the formula: 1 lux = 0.00146 ΞΌmol/mΒ²/s.
What is the relationship between lux and PAR?
PAR measures light within the spectral range plants can use for photosynthesis, while lux is a broader measure of illuminance.
Can I use this calculator for indoor plant lighting?
Yes, this conversion helps in setting up appropriate lighting conditions for indoor plants based on their PAR requirements.
How accurate is the conversion from lux to W/mΒ²?
The conversion factor of 0.00146 ΞΌmol/mΒ²/s is a standard approximation and may vary slightly depending on specific light sources.
What units are used in this calculator?
This calculator uses lux for illuminance and W/mΒ² for Photosynthetically Active Radiation (PAR).
Is there a difference between lumens and lux?
Yes, lumens measure the total amount of light emitted by a source, while lux measures the amount of light falling on a surface per unit area.
Can I convert W/mΒ² back to lux using this calculator?
No, this calculator is specifically for converting lux to W/mΒ². For the reverse conversion, you would need to use the inverse of the conversion factor.
