The footcandle hour (fc·h) is a unit of measurement that quantifies the total illuminance received over a specified period of time. It is derived from the footcandle, which measures the amount of light that falls on a surface from a light source. One footcandle is defined as the illuminance produced by one lumen per square foot. The footcandle hour, therefore, provides a comprehensive understanding of light exposure over time, making it essential for various applications in lighting design, photography, and horticulture.
The footcandle hour is standardized in the International System of Units (SI) and is widely used in the United States and other countries that follow the imperial system. It is crucial for professionals in fields such as architecture, agriculture, and photography to ensure consistent lighting conditions and optimize light usage.
The concept of measuring light exposure dates back to the early 20th century when scientists began to study the effects of light on human health and plant growth. The footcandle unit was established to provide a practical means of measuring light intensity in indoor and outdoor environments. Over the years, the footcandle hour has evolved into a vital tool for professionals who require precise control over lighting conditions.
To calculate footcandle hours, multiply the illuminance in footcandles by the duration in hours. For example, if a space is illuminated at 50 footcandles for 4 hours, the total light exposure would be: [ \text{Footcandle Hours} = 50 , \text{fc} \times 4 , \text{h} = 200 , \text{fc·h} ]
Footcandle hours are particularly useful in various industries:
To use the Footcandle Hour tool effectively, follow these steps:
What is a footcandle hour? A footcandle hour is a unit of measurement that indicates the total illuminance received over a specified period of time, combining both light intensity and duration.
How do I convert footcandles to footcandle hours? To convert footcandles to footcandle hours, multiply the illuminance in footcandles by the time in hours.
What industries use footcandle hours? Footcandle hours are commonly used in agriculture, photography, and interior design to measure and optimize lighting conditions.
How can I measure footcandles accurately? Use a light meter to measure the illuminance in footcandles accurately before inputting the value into the tool.
Why is it important to monitor footcandle hours? Monitoring footcandle hours helps ensure that spaces receive adequate lighting for their intended use, promoting health, productivity, and aesthetic appeal.

Nits, represented by the symbol "nt," is a unit of measurement for luminance, which quantifies the amount of light emitted or reflected from a surface in a given direction. It is essential in fields such as photography, display technology, and lighting design, where understanding light intensity is crucial for optimal visual performance.
The nit is part of the International System of Units (SI) and is defined as one candela per square meter (cd/m²). This standardization allows for consistent measurements across various applications, ensuring that professionals can rely on accurate data when designing and evaluating lighting conditions.
The term "nit" originates from the Latin word "nitere," meaning "to shine." The concept of measuring light intensity has evolved significantly since the early days of photometry. The introduction of the nit as a standard unit in the 20th century marked a pivotal moment in the field, providing a clear and concise way to express luminance in various applications, from television screens to architectural lighting.
To illustrate how to calculate luminance in nits, consider a display that emits 500 candelas of light over an area of 1 square meter. The luminance can be calculated as follows:
Luminance (nt) = Luminous intensity (cd) / Area (m²)
Luminance (nt) = 500 cd / 1 m² = 500 nt
Nits are widely used in various industries, including:
