About these measurements

Illuminance is luminous flux falling on a surface per unit area.

The base reference used here is the lux. One femtolux is 1e-15 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.
