Enter the total candelas and the total area (m^2) into the Calculator. The calculator will evaluate the Candela Per Square Meter. 

Candela Per Square Meter Formula

CPSM = C / A

Variables:

  • CPSM is the Candela Per Square Meter (candela/m^2)
  • C is the total candelas
  • A is the total area (m^2)

To calculate Candela Per Square Meter, divide the total candelas by the area in square meters.

How to Calculate Candela Per Square Meter?

The following steps outline how to calculate the Candela Per Square Meter.


  1. First, determine the total candelas. 
  2. Next, determine the total area (m^2). 
  3. Next, gather the formula from above = CPSM = C / A.
  4. Finally, calculate the Candela Per Square Meter.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total candelas = 91203

total area (m^2) = 1123

Frequently Asked Questions

What is a candela and how is it used in lighting?

A candela is the SI unit of luminous intensity, representing the amount of light emitted in a particular direction. It is used in lighting to quantify the intensity of light sources, such as bulbs and LEDs, in a specific direction rather than the total light emitted.

Why is measuring Candela Per Square Meter important in lighting design?

Measuring Candela Per Square Meter is crucial in lighting design because it helps in assessing the brightness of light that falls on a given area. This measurement is essential for ensuring that spaces are lit adequately according to their purpose, enhancing visibility, ambiance, and energy efficiency.

Can the Candela Per Square Meter value affect the mood or atmosphere of a room?

Yes, the Candela Per Square Meter value can significantly affect the mood or atmosphere of a room. Different lighting intensities can evoke different feelings; for example, a lower intensity can create a cozy and relaxed atmosphere, while higher intensities are often used in workspaces to increase alertness and productivity.

How does the area of a space influence the calculation of Candela Per Square Meter?

The area of a space directly influences the calculation of Candela Per Square Meter because the same amount of light spread over a larger area will result in a lower intensity per unit area. This is why larger spaces may require more powerful lighting sources to achieve the same level of brightness as in smaller spaces.
