How to convert nanometers to light years
There are 9.46073 × 10²⁴ nanometers in one light year, so divide the number of nanometers by 9.46073 × 10²⁴.
ly = nm ÷ 9.46073 × 10²⁴
1 nm = 1.057001 × 10⁻²⁵ ly · 1 ly = 9.46073 × 10²⁴ nm
Worked example
To convert 5 nanometers to light years: 5 nm ÷ 9.46073 × 10²⁴ = 5.285004 × 10⁻²⁵ ly.
About nanometers (nm)
A nanometer is one billionth of a metre. It is used for wavelengths of light and the size of molecules and computer chip features.
About light years (ly)
A light year is the distance light travels in one Julian year, about 9.46 trillion km. It is used for distances between stars.
