60 lux over an area of 1 square meter equals 60 lumens. This means if you have a surface receiving 60 lux of illuminance and the surface area is exactly 1 square meter, the total luminous flux falling on it will be 60 lumens.
Lux measures illuminance, which is lumens per square meter. To convert lux to lumens, you multiply the lux value by the area in square meters. Without the area, lux alone can’t give total lumens, but assuming 1 m², the conversion is direct.

Conversion Formula
The formula to convert lux to lumens depends on the surface area illuminated:
Lumens = Lux × Area (in square meters)
Lux is a measure of luminous flux per unit area, so multiplying it by the area gives the total luminous flux in lumens. This works because lux equals lumens per square meter. If you know the lux value and the size of the surface, you can find total lumens.
Example:
- Given: 60 lux illuminance and area = 1 square meter
- Calculate: 60 lux × 1 m² = 60 lumens
- If area = 2 m², then 60 lux × 2 m² = 120 lumens
Conversion Example
- Example 1: Convert 45 lux to lumens over 1 m²
- Lux value = 45
- Area = 1 m²
- Calculate: 45 × 1 = 45 lumens
- Example 2: Convert 70 lux to lumens over 3 m²
- Lux value = 70
- Area = 3 m²
- Calculate: 70 × 3 = 210 lumens
- Example 3: Convert 50 lux to lumens over 0.5 m²
- Lux value = 50
- Area = 0.5 m²
- Calculate: 50 × 0.5 = 25 lumens
- Example 4: Convert 80 lux to lumens over 2.5 m²
- Lux value = 80
- Area = 2.5 m²
- Calculate: 80 × 2.5 = 200 lumens
- Example 5: Convert 90 lux to lumens over 0.75 m²
- Lux value = 90
- Area = 0.75 m²
- Calculate: 90 × 0.75 = 67.5 lumens

The chart shows lux values from 35 to 85, assuming the area is 1 square meter, so the lumens equal the lux. To find lumens for different surfaces multiply the lux in the chart by your surface area.

Conversion Definitions
Lux: Lux is a unit of illuminance measuring luminous flux per unit area, equal to one lumen per square meter. It indicates how much light is spread over a surface, helping gauge brightness in environments or lighting setups.
Lumens: Lumens measure luminous flux, the total quantity of visible light emitted by a source per second. It reflects how much light is produced, regardless of direction or area, used to describe brightness of bulbs or lamps.
Conversion FAQs
Can I convert 60 lux to lumens without knowing the area?
No, lux is lumens per square meter, so you must know the illuminated area to find total lumens. Without area, lux only tells light intensity on a surface, not the total light output.
What happens if the surface area is larger than 1 m²?
If the area increases, the total lumens increase proportionally. For example, 60 lux over 2 m² equals 120 lumens, since lumens = lux multiplied by area.
Is 60 lumens bright enough for reading?
60 lumens is generally low for reading, because reading requires higher illuminance levels. While 60 lux over 1 m² equals 60 lumens, better results come from higher lumens or focused lighting.
Why does lux depend on area but lumens does not?
Lux measures light intensity per unit area, so it depends on surface size. Lumens measure total light output from a source without regard to area, making it area independent.
How accurate is the lux to lumens conversion?
Conversion is accurate only when the surface area is known and uniform illuminance is assumed. Variations in surface shape or light distribution can affect precision.
