Lumen per Square Meter (lm/m²) in Illuminance

What is Lumen per Square Meter (lm/m²)

Lumen per square meter, often abbreviated as lm/m², is a unit of measurement that quantifies illuminance. Illuminance refers to the amount of luminous flux (light) that falls on a surface per unit area. This measurement is essential for understanding how well a space is lit, contributing to safety, comfort, and productivity in various environments.

The lumen (lm) is the unit of luminous flux, and one lumen represents the amount of light emitted by a source that produces a flow of light perceived by the human eye. When this luminous flux is spread over an area of one square meter, the resulting illuminance is measured in lm/m². This can also be referred to as lux (lx), where 1lx=1lm/m2.

Understanding lm/m² is crucial for designing efficient lighting systems, whether for homes, offices, or public spaces. It allows designers and engineers to determine how much light is necessary for a specific area, ensuring that it meets standards for visibility and functionality.

Common conversions values

When dealing with lm/m², it can be helpful to convert this unit into other common units of measurement for illuminance. Here are some common conversion values:

• 1(lm/m2)=0.0001(lm/cm2)

This means that for every 1 lumen per square meter, you have 0.0001 lumen per square centimeter.

• 1(lm/m2)=0.09290304(lm/ft2)

Thus, the illuminance of 1 lm/m² is equivalent to approximately 0.0929 lumens per square foot.

• 1(lm/m2)=0.00064516(lm/in2)

In this conversion, 1 lumens per square meter equals about 0.00064516 lumens per square inch.

• 1(lm/m2)=0.09290304(fc)

This means that the illuminance of 1 lm/m² translates to approximately 0.0929 foot-candles (fc).

• Since 1 lm/m² = 1 lx, no conversion factor is required here.

• 1(lm/m2)=0.0001(ph)

For illuminance in phot, the conversion shows that 1 lm/m² is the same as 0.0001 phot.

Converting illuminance values allows better understanding and usage of lighting in different applications, helping to create bright and inviting spaces. Knowing these common conversions can aid architects, designers, and individuals alike when considering light requirements for various settings.
