1. What is a Lux to Nits Calculator?

Definition: This calculator converts illuminance (lux) to luminance (nits) measurements.

Purpose: It helps professionals in lighting design, photography, and display technology understand equivalent brightness measurements.

2. How Does the Calculator Work?

The calculator uses the simple conversion:

Where:

• 1 lux (lx) — 1 lumen per square meter (lm/m²)
• 1 nit (cd/m²) — 1 candela per square meter

Explanation: While lux measures illuminance (light falling on a surface), nits measure luminance (light emitted by a surface). The 1:1 ratio applies when converting between these units for practical purposes.

3. Importance of Lux-Nits Conversion

Details: Understanding both measurements is crucial for:

• Display brightness specifications (nits)
• Lighting design and photometry (lux)
• Camera exposure settings
• Scientific research involving light measurement

4. Using the Calculator

Tips: Simply enter the lux value to get the equivalent in nits. The conversion is direct with no additional factors needed.

5. Frequently Asked Questions (FAQ)

Q1: Are lux and nits really the same?
A: While numerically equivalent (1 lux = 1 nit), they measure different aspects of light - lux measures incident light, nits measure emitted light.

Q2: When would I need this conversion?
A: When comparing display brightness (nits) with ambient light levels (lux), or when working with equipment that uses different measurement units.

Q3: Does this conversion work for all light sources?
A: The 1:1 ratio is a practical approximation. For precise scientific work, consider the specific properties of your light source and surface.

Q4: What's a typical nit value for displays?
A: Smartphones: 400-1000 nits, TVs: 100-2000 nits, HDR displays: up to 4000 nits.

Q5: What's a typical lux value for environments?
A: Office lighting: 300-500 lux, Overcast day: 1000 lux, Sunny day: 10,000-25,000 lux.
