Convert luminous flux (lumens) to luminance (nits) based on screen area

Input Parameters

Calculation Results

Calculation Formula

Luminance (nits) = Luminous Flux (lumens) / (Width (m) × Height (m))

Where:
Luminance (nits) - The amount of light emitted through a specific area
Luminous Flux (lumens) - The total amount of visible light emitted
Width (m) × Height (m) - The area of the screen in square meters

Result

Luminance:

0.00 nit

Area:

0.00 m²

Lumens to Nits Converter Calculator Usage Guide

Learn how to use the Lumens to Nits Converter calculator and its working principles

How to Use This Calculator

  1. Enter the luminous flux in lumens (lm)
  2. Enter the width of your display screen in meters (m)
  3. Enter the height of your display screen in meters (m)
  4. Click the "Calculate" button to compute the luminance in nits
  5. Click "Reset" to clear all inputs and start over

Understanding the Formula

Luminance (nit) is calculated by dividing the total luminous flux (lumens) by the display area (square meters). The formula is:

Luminance (nit) = Luminous Flux (lumens) / (Width (m) × Height (m))

This calculation helps you understand how bright a display is relative to its size. A higher nit value means a brighter display for the same amount of light.

Practical Applications

This calculator is useful for:

  • Comparing the brightness of different display sizes
  • Designing media rooms or home theaters
  • Calibrating professional displays in controlled environments
  • Evaluating screen brightness for outdoor advertising

Example Calculation

For a 100-inch (2.54m wide) 16:9 TV with a luminous flux of 800 lumens:

  1. Width = 2.54 meters
  2. Height = 2.54 × 9/16 = 1.43 meters
  3. Area = 2.54 × 1.43 = 3.64 m²
  4. Luminance = 800 / 3.64 = 220.6 nits
