Spectral Radiant Flux Converter FAQ

Are the conversions exact?

Yes. We use exact scaling between W/nm, mW/nm, and W/µm.

Can I convert between W/nm and mW/nm?

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

Does this handle very small or very large spectral radiant flux values?

Yes. You can convert down to mW/nm or up to W/µm with high precision using Decimal arithmetic.
