Nanometers to Parsecs

Nanometer

A nanometer (nm) is a microscopic metric unit equal to one-billionth of a meter. It is used in science and technology to measure atoms, wavelengths of light, and semiconductor components. Nanometers help describe the invisible structures that make modern electronics work.

Because nanometers are so tiny, converting to micrometers or meters helps give context to scientific data—especially in materials research and optics.

Parsec

A parsec (pc) is a unit of length used in astronomy to measure huge distances between celestial objects. It equals about 3.26 lightyears, or 31 trillion kilometers (19 trillion miles). The name comes from “parallax arcsecond,” referring to the way astronomers calculate distances by measuring the slight shift of stars in the sky.

The parsec helps express distances that are far too vast for lightyears or kilometers. Converting parsecs to other astronomical units makes the scale of the universe easier to understand for scientists and space explorers.
