Some Important Units of Long Distances

  • Light year = Distance traveled by light in vacuum in one year = 9.46 x 1015 m ~ 1016 m.
  • 1 Parsec ( Parallactic second ) is the distance corresponding to a parallex of one second of arc, 1 Parsec = 3.08 x 1016 m = 3.26 light years.

Some Important Units of Short Distances

  • 1 micron ( 1 µ ) = 10-4 cm, 10 -6 m
  • 1 Angstrom ( 1 Å ) = 10 -8 cm, 10 -10 m
  • 1 Fermi ( 1F ) = 10 -13 cm, 10 -15 m
  • 1 x U = 10 -11 cm, 10 -13 m
