Unit definition
Nits (nt) One nits equals 1 candela per square metre.
Unit history
Nits is represented here using its modern SI definition or an internationally accepted relationship to an SI base unit.
Step by step
1. Parse the value, including fractions.
2. Convert nt to candela per square metre.
3. Convert the base value to cd/m² and apply your display precision.
Understand the result before using it
Nits to Candelas per square metre converts a value measured in Nits (nt) into the equivalent value in Candelas per square metre (cd/m²). The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
result = input × 1 ÷ 1
Assumptions
- Nits and Candelas per square metre represent the same luminance quantity.
- The input is expressed in nt; the output is expressed in cd/m².
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 nt = 1 cd/m². For another value, apply the same relationship and round only to the precision your source measurement supports.
When to use it
Good uses
- Read a nt measurement in a document that expects cd/m².
- Compare a nits value with a value reported in candelas per square metre.
- Check the nt-to-cd/m² arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- Decibel sound-pressure level is logarithmic and depends on the stated reference pressure.
- Round the output to a precision justified by the original measurement.
- Verify safety-critical, regulated, laboratory, and contractual conversions against the controlling standard.

Questions about this calculation
How do I convert Nits to Candelas per square metre?
result = input × 1 ÷ 1 Using the displayed relationship, 1 nt equals 1 cd/m².
How many Candelas per square metre are in one Nits?
One Nits is 1 Candelas per square metre. The displayed digits may be rounded.
Can I reverse the nt to cd/m² conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts cd/m² back to nt.
Is the Nits to Candelas per square metre result exact?
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
