Radiant Flux Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radiant Flux = Radiant Intensity*Solid Angle for Radiance
dΦ = I_r*dω
This formula uses 3 Variables

Variables Used

Radiant Flux - (Measured in Erg per Second) - Radiant Flux is emitted within the small wavelength range of a spectral line.
Radiant Intensity - (Measured in Watt per Steradian) - Radiant Intensity is the radiant flux emitted, reflected, transmitted or received, per unit solid angle.
Solid Angle for Radiance - (Measured in Radian) - Solid Angle for Radiance is a measure of the amount of the field of view from some particular point that a given object covers.

STEP 1: Convert Input(s) to Base Unit

Radiant Intensity: 1.2 Watt per Steradian --> 1.2 Watt per Steradian No Conversion Required
Solid Angle for Radiance: 0.017 Radian --> 0.017 Radian No Conversion Required
