Summary

Enter a luminance value in nits and instantly see the equivalent in cd/m² — the values are equal by definition, with a brightness reference table for context.

How it works

  1. Enter a luminance value in nits in the input field.
  2. The converter applies the exact factor: 1 nt = 1 cd/m².
  3. The result in cd/m² appears instantly as you type.
  4. Use the Copy button to copy the result to your clipboard.
  5. Scroll down to the reference table to compare your value against common display and lighting brightness levels.

Use cases

  • Verify luminance specs when a datasheet lists brightness in nits but your workflow uses cd/m².
  • Compare display brightness ratings across manufacturer specs that use different notation.
  • Translate HDR peak brightness values (nits) into cd/m² for photometric calculations.
  • Confirm display calibration targets when switching between monitor documentation formats.
  • Check ambient lighting luminance for photography or cinematography planning.
  • Understand brightness levels when reading TV or monitor reviews that mix notation.
