Convert between watt per square meter per steradian (W/m²·sr), kilowatt per square meter per steradian (kW/m²·sr), milliwatt per square centimeter per steradian (mW/cm²·sr), and microwatt per square centimeter per steradian (µW/cm²·sr). Exact relationships are used, including 1 mW/cm²·sr = 10 W/m²·sr.

Radiance Converter FAQ

Are the conversions exact?

Yes. We use exact scaling between W/m²·sr, kW/m²·sr, mW/cm²·sr, and µW/cm²·sr.

Can I convert between W/m²·sr and mW/cm²·sr?

Yes. Enter your value in W/m²·sr and select mW/cm²·sr as the target (or vice versa); results update instantly as you type.

Does this handle very small or very large radiance values?

Yes. You can convert down to µW/cm²·sr or up to kW/m²·sr with high precision using Decimal arithmetic.
