Spectral Radiant Exposure Converter FAQ
Are the conversions exact?
Yes. We use exact scaling between J/m²·nm, kJ/m²·nm, mJ/cm²·nm, and J/m²·µm.
Can I convert between J/m²·nm and mJ/cm²·nm?
Yes. Enter your value in J/m²·nm and select mJ/cm²·nm as the target (or vice versa); results update instantly as you type.
Does this handle very small or very large spectral radiant exposure values?
Yes. You can convert down to mJ/cm²·nm or up to J/m²·µm with high precision using Decimal arithmetic.
