The candela per square meter (cd/m²), commonly referred to as "nits," is a unit of measurement for luminance. It quantifies the amount of light emitted from a surface in a specific direction, per unit area. This measurement is crucial for assessing the brightness of displays, lighting fixtures, and other surfaces that emit light.
The candela per square meter is standardized by the International System of Units (SI) and is derived from the base unit of luminous intensity, the candela (cd). One candela per square meter is equivalent to one candela of luminous intensity emitted from a surface area of one square meter. This standardization ensures consistency in measuring brightness across various applications.
The concept of luminance has evolved significantly since the early days of photometry. The candela was defined in the late 19th century, and the term "candela per square meter" was introduced as a way to quantify brightness in a more practical manner. Over the years, advancements in technology have led to the widespread use of this measurement in various fields, including television, computer displays, and architectural lighting.
To illustrate the use of the candela per square meter, consider a light source that emits 1000 candelas uniformly across a surface area of 2 square meters. The luminance can be calculated as follows:
[ \text{Luminance (cd/m²)} = \frac{\text{Luminous Intensity (cd)}}{\text{Area (m²)}} ]
[ \text{Luminance} = \frac{1000 , \text{cd}}{2 , \text{m²}} = 500 , \text{cd/m²} ]
This calculation shows that the surface has a luminance of 500 cd/m².
The candela per square meter is widely used in various industries, including:

Lux per hour (lx/h) is a unit of measurement that quantifies the amount of illuminance received over a specified period. It is derived from the lux, which measures luminous flux per unit area. This metric is crucial for evaluating lighting conditions in various environments, ensuring that spaces are adequately illuminated for safety and comfort.
The lux is standardized by the International System of Units (SI), where 1 lux equals 1 lumen per square meter. Lux per hour, therefore, represents the total illuminance received over the course of an hour, making it a valuable metric for assessing lighting efficiency and energy consumption.
The concept of measuring light intensity has evolved significantly since the early days of photometry. Initially, light was measured using candles and other rudimentary sources. The introduction of the lux as a standard unit in the 20th century marked a significant advancement in the field of lighting design and engineering, allowing for more precise calculations and comparisons.
To illustrate the use of lux per hour, consider a room with an illuminance of 300 lux. If the lights are on for 5 hours, the total illuminance received would be calculated as follows:
Lux per hour is commonly used in various fields, including architecture, photography, horticulture, and workplace safety. It helps professionals determine the adequacy of lighting in different settings, ensuring compliance with safety standards and enhancing productivity.
To use the lux per hour tool effectively, follow these steps:
What is lux per hour (lx/h)? Lux per hour is a measurement of the total illuminance received over a specified time, expressed in lux multiplied by hours.
How do I convert lux to lux per hour? To convert lux to lux per hour, multiply the lux value by the number of hours the light is on.
What is the significance of measuring lux per hour? Measuring lux per hour helps assess the adequacy of lighting in various environments, ensuring safety and comfort.
Can I use lux per hour for outdoor lighting assessments? Yes, lux per hour is applicable for both indoor and outdoor lighting assessments, helping to ensure adequate illumination in all settings.
How can I improve my lighting efficiency based on lux per hour calculations? By analyzing lux per hour values, you can identify areas where lighting can be reduced or optimized, leading to energy savings and improved lighting quality.
