Converting from Parsec (pc) to Light Hour (lh) | Astronomy distance

What is Parsec (pc)

A Parsec (pc) is a unit of distance used in astronomy to measure large distances to objects outside the Solar System, representing the distance at which an object would have a parallax angle of one arcsecond. One Parsec is equivalent to approximately 3.26 light-years.

What is Light Hour (lh)

A Light Hour (lh) is a unit of length representing the distance that light travels in one hour. It is commonly used in astronomy to measure the vast distances in the universe. One Light Hour is equivalent to the distance light travels in vacuum in one hour, which is approximately 1.079 billion kilometers.

Conversion Formulas

To convert from Parsec to Light Hour and vice versa, you can use the following formulas:

1pc=28590.87lh

1lh=0.0000349762pc

Examples

1. Converting 4 Parsecs to Light Hours:

4pc×28590.87=114363.5lh

2. Converting 13 Light Hours to Parsecs:

13lh×0.0000349762=0.0004546906pc

Additional conversions:

• 5 Parsecs = 142954.3 Light Hours
• 4 Light Hours = 0.0001399048 Parsecs
