Radiant Intensity Converter FAQ
Are the conversions exact?
Yes. We use exact scaling between W/sr, mW/sr, and higher SI prefixes.
Can I convert between W/sr and mW/sr?
Yes. Enter your value in W/sr and select mW/sr as the target (or vice versa); results update instantly as you type.
Does this handle very small or very large radiant intensity values?
Yes. You can convert down to mW/sr or up to MW/sr with high precision using Decimal arithmetic.
