60 lux corresponds to 60 lumens per square meter assuming a surface area of 1 square meter, so the total lumens for 60 lux over 1 m² is 60 lumens.
Lux measures illuminance, meaning the amount of light falling on a surface, while lumens measure luminous flux, or the total light emitted by a source. To convert lux to lumens, you multiply the illuminance by the surface area receiving light.

Conversion Formula
The formula to convert lux to lumens depends on the area illuminated. Lux (lx) equals lumens (lm) divided by area in square meters (m²). So to find lumens from lux, multiply lux value by the area:
Lumens = Lux × Area (m²)
This works because lux tells you how many lumens spread over each square meter, so multiplying by the number of square meters reverses the calculation. For example, if a surface receives 60 lux and has an area of 1 m²:
- Lux = 60 lx
- Area = 1 m²
- Lumens = 60 × 1 = 60 lm
If the area was 2 m², then lumens would be 60 × 2 = 120 lm.
Conversion Example
- Convert 45 lux over 2 m²:
- Start with 45 lx
- Area is 2 m²
- Lumens = 45 × 2 = 90 lm
- Convert 70 lux over 0.5 m²:
- Lux = 70 lx
- Area = 0.5 m²
- Lumens = 70 × 0.5 = 35 lm
- Convert 80 lux over 3 m²:
- 80 lx × 3 m²
- Lumens = 240 lm
- Convert 50 lux over 1.5 m²:
- 50 × 1.5 = 75 lm
- Convert 90 lux over 4 m²:
- 90 × 4 = 360 lm

Conversion Definitions
Lux: Lux is a unit measuring illuminance, which is the quantity of visible light falling on a surface per unit area. It expresses how bright an area appears, calculated by dividing luminous flux in lumens by the surface area in square meters. Lux values vary depending on light intensity and distance.
Lumens: Lumens measure luminous flux, representing the total amount of visible light emitted by a source in all directions. Unlike lux, which depends on area, lumens quantify the overall light output regardless of distance or surface size, helping to compare brightness of different light sources.
Conversion FAQs
Can I convert lux to lumens without knowing the area?
No, converting lux to lumens requires knowing the illuminated surface area because lux measures light per unit area. Without area, you can’t determine total lumens, only the intensity per square meter.
Why does the area affect the conversion between lux and lumens?
Lux is lumens spread over area, so larger surface means more total lumens for the same lux value. Changing area changes the total light quantity, but lux stays constant as it’s per square meter.
Is 60 lux always equal to 60 lumens?
Only if the light falls on exactly 1 square meter. If the surface is bigger or smaller, lumens will be lux multiplied by that area, so 60 lux can represent different lumens amounts.
How precise is the lux to lumens conversion?
The conversion depends on accurate measurement of area and uniform light distribution. If surface is irregular or not evenly lit, the calculation may have errors or only approximate values.
What applications use lux to lumens conversion?
Lighting design, photography, interior planning, and horticulture use these conversions to decide light levels needed for spaces or objects, ensuring proper illumination intensity and energy efficiency.
