An obscure unit of velocity - attoparsecs per microfortnight (25 feb 11)

A parsec is an astronomical unit, approximately 3.26 light years

A fortnight is two weeks

An attoparsec is 10 ^-18 parsecs

A microfortnight is a millionth of two weeks

'Attoparsecs per microfortnight' is about one inch per second:

In Ruby, to convert attoparsecs per microfortnight into inches per second, multiply by:

  ( ((1.9174 * 10**13)* 10**-18) * (12*3*1760) ) / ( (60*60*24*14) / 1000000.0 )
