60 lux corresponds to 60 lumens when the illuminated surface area is exactly 1 square meter. This is because lux measures luminous flux per unit area, so converting lux to lumens requires knowing the area involved.
Lux (lx) is the measure of illumination on a surface, whereas lumens (lm) indicate the total light output emitted by a source. To convert from lux to lumens, you multiply the lux value by the area over which the light spreads, expressed in square meters.

Conversion Formula
To convert lux to lumens, the formula is:
Lumens (lm) = Lux (lx) × Area (m²)
This works because lux measures how much light hits a surface area. If you know how big the area is, multiplying lux by that area gives you the total light output in lumens.
For example, if you have 60 lux illuminating 1 square meter:
- Lux = 60 lx
- Area = 1 m²
- Lumens = 60 × 1 = 60 lm
If the area changes, the lumens change proportionally. For example, 60 lux over 2 m² would be 120 lumens.
Conversion Example
- Example 1: 45 lux over 1 m²
- Lux value given: 45 lx
- Area considered: 1 m²
- Calculation: 45 × 1 = 45 lumens
- Example 2: 75 lux over 2 m²
- Lux value given: 75 lx
- Area considered: 2 m²
- Calculation: 75 × 2 = 150 lumens
- Example 3: 50 lux over 0.5 m²
- Lux value given: 50 lx
- Area considered: 0.5 m²
- Calculation: 50 × 0.5 = 25 lumens
- Example 4: 80 lux over 1.5 m²
- Lux value given: 80 lx
- Area considered: 1.5 m²
- Calculation: 80 × 1.5 = 120 lumens

Conversion Definitions
Lux: Lux is a unit measuring the amount of light that falls on a surface per square meter. It quantifies illumination intensity, representing how bright a surface appears under a light source. One lux equals one lumen per square meter, linking light output to area coverage.
Lumens: Lumens is a unit measuring the total amount of visible light emitted by a source. It accounts for the brightness perceived by the human eye, regardless of direction. Higher lumens indicate brighter light output, independent from how that light is distributed across an area.
Conversion FAQs
Can I convert lux to lumens without knowing the surface area?
No, because lux measures illumination per unit area, lumens depend on the total area illuminated. Without knowing the area, you cannot accurately convert lux to lumens. The formula requires both lux and surface area for conversion.
Does the shape of the illuminated area affect the lux to lumens conversion?
The shape itself doesn’t affect the conversion directly, only the total surface area matters. Whether the surface is square, circular, or irregular, lumens calculation uses the area in square meters multiplied by lux value.
Why is 60 lux equal to 60 lumens only if area is 1 square meter?
Because lux is lumens per square meter, when the area equals exactly one square meter, the lux value and lumens become numerically equal. If the area changes, the total lumens change proportionally to the area.
Can ambient light influence lux to lumens conversion?
Ambient light affects lux measurements because lux gauges illumination on a surface. However, lumens measure total light output from the source, so ambient light does not alter lumens but changes the lux reading on surfaces.
Is the conversion different indoors versus outdoors?
The conversion formula remains same indoors or outdoors, but outdoor conditions may cause lux readings to fluctuate due to environmental factors like sunlight and shadows, which can affect the accuracy of lux measurements.
