picolux to nanolux
Convert picolux (plx) to nanolux (nlx). Use an editable illuminance converter, conversion formula, and reference table.
1 plx = 0.001 nlx
Conversion formula
One picolux equals 0.001 nanolux. Multiply your value in picolux by this factor to get nanolux. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 picolux:5 × 0.001 = 0.005 nlx

About these measurements
Illuminance is luminous flux falling on a surface per unit area.
The base reference used here is the lux. One picolux is 1e-12 base units; one nanolux is 1e-9 base units.
Important distinctions
One lux is one lumen per square meter.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert plx to nlx?
Multiply the quantity in plx by 0.001. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the nanolux to picolux converter.
