How many cd/m² is 1 stilb?

1 stilb (sb) equals exactly 10,000 candela per square meter (cd/m²). This is a fixed, exact conversion with no rounding.

What is a stilb used for?

The stilb is a CGS (centimetre-gram-second) unit of luminance. It is mostly used in older scientific literature and some specialized photometric instruments. Modern standards use cd/m², also called the nit in display contexts.

Is cd/m² the same as a nit?

Yes. One nit equals one candela per square meter (1 nit = 1 cd/m²). "Nit" is an informal name commonly used in display and screen brightness specifications.

What is the formula for stilb to cd/m²?

cd/m² = stilb × 10,000. To reverse: stilb = cd/m² ÷ 10,000.

What is a typical luminance in stilb for a monitor?

A typical monitor at 300 cd/m² equals 0.03 stilb. HDR displays at 1,000 cd/m² equal 0.1 stilb. The stilb is a large unit, so most display values are fractions of a stilb.

Summary

Convert luminance from stilb (sb) to candela per square meter (cd/m²). 1 sb = 10,000 cd/m².

How it works

Enter a luminance value in stilb (sb) in the input field.
The converter multiplies the value by 10,000 (the exact conversion factor).
The result in candela per square meter (cd/m²) appears instantly.
Use the swap button to reverse the conversion (cd/m² → stilb).
Copy the result with one click for use elsewhere.

Use cases

Convert old photometric data expressed in stilb to modern SI units (cd/m²).
Translate CGS luminance measurements for use in display calibration workflows.
Cross-reference scientific literature that mixes CGS and SI luminance units.
Verify luminance sensor readings when the sensor outputs in stilb.
