attoparsec

The Free On-line Dictionary of Computing (foldoc)

About 31 mm (one inch). "atto-" is the
standard {SI} {prefix} for multiplication by 10^-18. A parsec
(parallax-second) is 3.26 light-years; an attoparsec is thus
3.26 * 10^-18 light years. Thus, one attoparsec per
{microfortnight} is about one inch per second.

This unit is reported to be in use (though probably not very
seriously) among hackers in the UK.

[{Jargon File}]

(1996-12-08)

The Jargon File, version 4.4.8 (jargon)

attoparsec: n. About an inch. atto- is the standard
SI prefix for multiplication by
10^-18. A
parsec (parallax-second) is 3.26 light-years; an attoparsec is thus
3.26 ×
10^-18 light years, or about 3.1
cm (thus, 1 attoparsec/microfortnight equals about 1
inch/sec). This unit is reported to be in use (though probably not very
seriously) among hackers in the U.K. See
micro-.
