(b) (Metric System, Elec., Mech., etc.) A millionth part of;

The Jargon File (version 4.4.7, 29 Dec 2003):
1. Very small; this is the root of its use as a quantifier prefix.
2. A quantifier prefix, calling for multiplication by 10^-6 (see
quantifiers). Neither of these uses is peculiar to hackers, but hackers
tend to fling them both around rather more freely than is countenanced in
standard English. It is recorded, for example, that one CS professor used
to characterize the standard length of his lectures as a microcentury ?
that is, about 52.6 minutes (see also attoparsec, nanoacre, and
3. Personal or human-scale ? that is, capable of being maintained or
comprehended or manipulated by one human being. This sense is generalized
from microcomputer, and is esp. used in contrast with macro- (the
corresponding Greek prefix meaning ?large?).
4. Local as opposed to global (or macro-). Thus a hacker might say that
buying a smaller car to reduce pollution only solves a microproblem; the
macroproblem of getting to work might be better solved by using mass
transit, moving to within walking distance, or (best of all) telecommuting.
The Free On-line Dictionary of Computing (18 March 2015):
1. An SI prefix used to multiply the value of an SI
(Système International) unit by some power of ten.
2. In mathematics or programming, a
prefix operator is one that is written before its operand. In
a programming language using prefix notation, all operators
are prefix operators.
