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 sb and apply your display precision.
Understand the result before using it
Nits to Stilbs converts a value measured in Nits (nt) into the equivalent value in Stilbs (sb). 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 ÷ 10000
Assumptions
- Nits and Stilbs represent the same luminance quantity.
- The input is expressed in nt; the output is expressed in sb.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 nt = 0.0001 sb. 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 sb.
- Compare a nits value with a value reported in stilbs.
- Check the nt-to-sb 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.
