Unit definition
Candelas per square metre (cd/m²) One candelas per square metre equals 1 candela per square metre.
Unit history
Candelas per square metre 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 cd/m² to candela per square metre.
3. Convert the base value to nt and apply your display precision.
Understand the result before using it
Candelas per square metre to Nits converts a value measured in Candelas per square metre (cd/m²) into the equivalent value in Nits (nt). 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
- Candelas per square metre and Nits represent the same luminance quantity.
- The input is expressed in cd/m²; the output is expressed in nt.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 cd/m² = 1 nt. 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 cd/m² measurement in a document that expects nt.
- Compare a candelas per square metre value with a value reported in nits.
- Check the cd/m²-to-nt 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.
