The Kilometers to Mega-Parsecs calculator converts a measurement of length in kilometers to mega-parsecs.
INSTRUCTIONS: Choose units and enter the following:
- (km) This is the distance in kilometers
Mega-Parsec(Mpc): The calculator returns the distance in mega-parsecs. However, this can be automatically converted to other units via the pull-down menu.
The Math / Science
A parsec was traditionally defined as the distance where one astronomical unit subtends an angle of one arcsecond. A parsec was redefined in 2015 to `648000/π` astronomical units. A mega-parsec is one million parsecs.
Mega-parsecs are used in Astronomy Calculations when more conventional units such as kilometers are too small for easy comprehension, and the conversion from common length units to astronomical units is a simple linear transform for the distances to remote galaxies.
