60 lux on a surface with an area of 1 square meter corresponds to 60 lumens. This means when a light uniformly illuminates an area of 1 square meter with 60 lux, the total luminous flux falling on that area is 60 lumens.
Lux and lumens measure related but different things: lux measures illuminance (light per area), and lumens measure total light output. To convert lux to lumens, you multiply the lux value by the surface area in square meters where the light falls. Here, assuming 1 m², 60 lux equals 60 lumens.

Conversion Formula
The formula to convert lux (lx) to lumens (lm) depends on the surface area (A) in square meters receiving the light:
Lumens (lm) = Lux (lx) × Area (m²)
This works because lux measures luminous flux per unit area, so multiplying by area gives the total luminous flux in lumens.
For example, if you have 60 lux illuminating an area of 1 m²:
- Identify the lux value: 60 lx
- Identify the area: 1 m²
- Multiply lux by area: 60 × 1 = 60 lumens
If the area was 2 m² instead, then lumens would be 60 × 2 = 120 lumens.
Conversion Example
- Convert 45 lux to lumens on a 1.5 m² surface:
- Lux value: 45 lx
- Area: 1.5 m²
- Calculation: 45 × 1.5 = 67.5 lumens
- Convert 80 lux to lumens on a 0.75 m² surface:
- Lux: 80 lx
- Area: 0.75 m²
- Calculation: 80 × 0.75 = 60 lumens
- Convert 100 lux on 2 m²:
- Lux: 100 lx
- Area: 2 m²
- Calculation: 100 × 2 = 200 lumens
- Convert 55 lux on 0.9 m²:
- Lux: 55 lx
- Area: 0.9 m²
- Calculation: 55 × 0.9 = 49.5 lumens

Conversion Definitions
Lux: Lux is a unit measuring illuminance, which means the amount of luminous flux that hits a surface area. One lux equals one lumen per square meter. It describes how brightly a surface is lit, not the total light output.
Lumens: Lumens measure the total amount of visible light emitted by a source in all directions. It quantifies luminous flux, representing the perceived power of light, regardless of the area it covers.
Conversion FAQs
Can I convert lux to lumens without knowing the surface area?
No, converting lux to lumens requires knowing the surface area where the light is spread. Lux measures light per unit area; without area, you cannot determine total luminous flux in lumens.
Does a higher lux always mean more lumens?
Not necessarily. Lux depends on both lumens and area. A small area with moderate lumens can produce high lux, while a large area with the same lumens results in lower lux.
Why is 1 lux equal to 1 lumen per square meter?
Because lux is defined as luminous flux (in lumens) divided by area (in square meters). So when 1 lumen spreads evenly over 1 square meter, illuminance is 1 lux.
How does the angle of light affect lux to lumens conversion?
The lux to lumens conversion assumes uniform light distribution over an area. If light is angled or concentrated, the lux value changes locally, but total lumens remain constant. So angle affects lux measurement but not lumens directly.
Can two light sources with the same lux have different lumens?
Yes, if the illuminated areas differ. Same lux on a smaller area means fewer lumens, whereas same lux on a larger area means more lumens overall.
