milliwatt per steradian to watt per steradian converter

Convert milliwatt per steradian to watt per steradian in the Radiant intensity family. See a sample calculation, unit definitions, and the interactive converter.

Example conversion: 1 mW-sr

0.001 watt per steradian

This example is calculated from the same unit registry used by the interactive converter.

Formula and unit definitions

Convert radiant power per solid angle, distinct from photometric luminous intensity.

target value = source value × source factor ÷ target factor

Source unit: milliwatt per steradian (mW-sr), factor 0.001, offset 0.

Target unit: watt per steradian (W-sr), factor 1, offset 0.

Important note

The calculation is performed locally from the listed unit definitions. Display results are rounded for readability; high-precision and regulated work should use the governing standard and appropriate significant figures.

For high-precision, regulated or safety-critical use, check the underlying standard and its required precision. Historical and approximate units are identified in their names or family descriptions.
