SI Prefix Name

Go To

Names starting with Mega, Giga, Tera, Micro, Nano, or any other SI Prefix. Often, characters using this prefix won't actually be a power of ten greater than what the prefix is applied to.

Often used to imply "techno"-ness, due to their ubiquitous use in computational measurement (applied to space bytes, processor hertz, processor fabrication meters).

Commonly encountered prefixes include:

  • Femto- (10-15, f): The size scale of the atomic nucleus is measured in femtometers.
  • Advertisement:
  • Pico- (10-12, p): While individual atoms lie just below the nanometer scale, it is more common to express distances their in picometers. However, it's often used just to denote something really tiny, smaller than "Micro", that isn;t "Nano" as explained below.
  • Nano- (10-9, n): Denoting something tiny, but not as small as pico- or femto-. Particularly, Nanomachines exist at this scale.
  • Micro- (10-6, μ): Often used to denote small things that aren't "Nano" scale or smaller, and especially microscopic things. Individual cells are on the order of micrometers.
  • Milli- (10-3, m): Small objects that are just visible to the naked eye may be measured in millimeters. The smallest timescales in everyday life, such as the length of a frame, is measured in milliseconds.
  • Centi- (10-2, c): Many everyday things are measured in centimeters.
  • Advertisement:
  • Kilo- (103, k): The kilometer and kilobyte.
  • Mega- (106, M): Anything called "Mega" can be expected to be big or have something to do with being big.
  • Giga- (109, G): Expect anything named "Giga" to be huge, even bigger than "Mega".
  • Tera- (1012, T): The big daddy of the commonly encountered prefixes.
Other prefixes include yocto- (10-24, y), zepto- (10-21, z), atto- (10-18, a), deci- (10-1, d), deca- (101, da), hecto- (102, h), peta- (1015, P), exa- (1018, E), zetta- (1021, Z), and yotta- (1024, Y).
