Parsec (pc). A parsec is about 3.26 light years and is used by astronomers for distances between stars.
Millimeter (mm). A millimeter is one thousandth of a meter, used for small measurements such as thickness and rainfall.
There are 3.08568 × 10¹⁹ millimeters in one parsec.
Multiply the number of parsecs by 3.08568 × 10¹⁹. For example, 10 parsecs equal 3.08568 × 10²⁰ millimeters.
One millimeter equals 3.24078 × 10⁻²⁰ parsecs.
3.70281 × 10²⁰ millimeters. Other common values: 5 parsecs = 1.54284 × 10²⁰ millimeters and 100 parsecs = 3.08568 × 10²¹ millimeters.
