Luminance Converter

1 stilb (sb) equals 10000 candela per square metre (cd/m²).

How it works

• Expressed the source unit in candela per square metre using its exact factor.
• Divided by the target unit expressed in candela per square metre.
• Rounded the result to 12 significant digits.

1 stilb = 10000 cd_m2

• Both units measure luminance, so the conversion is a single exact multiplication.

Methodology

1. Express every unit as an exact factor to the candela per square metre base.
2. Multiply the input by the source factor and divide by the target factor.
3. Round the result to 12 significant digits so a convert-then-convert-back operation stays within floating-point tolerance.

Usage

1. Enter the value to convert.
2. Choose the source and target units.
3. Read the converted value and the conversion formula.

Limitations

Exact luminance factors

Every luminance unit is defined as an exact multiple of the candela per square metre, so the conversion is a single multiplication with no approximation beyond floating-point representation.
