About the Nanometer to Kilometer conversion
The conversion factor from Nanometer (nm) to Kilometer (km) is 1.0000e-12, meaning 1 nm = 1.0000e-12 km and inversely 1 km = 1.0000e+12 nm. That makes the Kilometer the larger of the two units in the length category, where the SI base unit is the meter. Every ratio here is derived from the SI/international definition rather than a rounded approximation, so results are stable across repeated conversions.
