1. What is NIT?

NIT (candelas per square meter) is a unit of luminance, measuring the intensity of light emitted from a surface per unit area. It is equivalent to cd/m² and commonly used in display technology to quantify screen brightness.

2. How Does the Calculator Work?

The calculator uses the NIT formula:

Where:

• \( Candelas \) — Luminous intensity (cd)
• \( m² \) — Surface area in square meters

Explanation: The formula calculates luminance by dividing the total luminous intensity by the area over which the light is distributed.

3. Importance of NIT Calculation

Details: Accurate NIT calculation is essential for evaluating display performance, ensuring proper brightness levels for various lighting conditions, and comparing different display technologies.

4. Using the Calculator

Tips: Enter candelas (luminous intensity) and area in square meters. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between NIT and lux?
A: NIT measures luminance (light emitted from a surface), while lux measures illuminance (light falling on a surface). 1 NIT = 1 cd/m².

Q2: What are typical NIT values for displays?
A: Standard monitors: 200-300 NIT, HDR displays: 400-1000+ NIT, outdoor displays: 1500-2500+ NIT.

Q3: How does NIT relate to screen visibility?
A: Higher NIT values provide better visibility in bright environments. Displays with 500+ NIT are suitable for outdoor use.

Q4: Can NIT be converted to other luminance units?
A: Yes, 1 NIT = 1 cd/m² = 0.0001 stilb = 0.2919 foot-lambert.

Q5: Why is NIT important for HDR content?
A: HDR content requires higher peak brightness (NIT values) to display a wider dynamic range and more vibrant colors.
