## ››Definition: Light-year

A light year, abbreviated ly, is the distance light travels in one year: roughly 9.46 × 1012 kilometres (9.46 petametres, or about 5.88 × 1012 (nearly six trillion) miles). More specifically, a light year is defined as the distance that a photon would travel, in free space and infinitely far away from any gravitational or magnetic fields, in one Julian year (365.25 days of 86400 seconds each).

## ››Definition: Nanometre

The SI prefix "nano" represents a factor of 10-9, or in exponential notation, 1E-9.

So 1 nanometre = 10-9 metre.
