About Watt per Steradian (W/sr)
The SI coherent derived unit of radiant intensity, defined as radiant power per unit solid angle (1 W/sr). The radiometric counterpart to photometric luminous intensity (candela).
History: Formulated in classical electromagnetic theory and codified by the CIPM for unweighted radiant flux angular distribution.
Common Uses: Infrared emitter beam strength, laser diode angular power specification, thermal radiation directional analysis.
About Kilowatt per Steradian (kW/sr)
One thousand watts per steradian (10ยณ W/sr).
History: Metric multiple applied in high-energy physics, directed energy systems, and astronomical radiant output.
Common Uses: Military infrared countermeasures, high-power pulsed laser beam directors, astronomical flare analysis.
โ Frequently Asked Questions
How many Kilowatts per Steradian are in 1 Watt per Steradian?
There are exactly 0.001 Kilowatts per Steradian in 1 Watt per Steradian (1 W/sr = 0.001 kW/sr).
What is the formula to convert Watt per Steradian to Kilowatt per Steradian?
The formula is: Kilowatt per Steradian = Watt per Steradian / 1000. Since 1 Kilowatt per Steradian = 1000 Watts per Steradian, divide the value in Watts per Steradian by 1000.
How do I convert 1 W/sr to kW/sr manually?
To convert 1 W/sr to kW/sr: apply the formula Kilowatt per Steradian = Watt per Steradian / 1000. Substituting gives: 1 / 1000 = 0.001 kW/sr.
