In virology, a plaque-forming unit (PFU) is a measure of the number of particles capable of forming plaques per unit volume, such as virus particles. It is a functional measurement rather than a measurement of the absolute quantity of particles: viral particles that are defective or which fail to infect their target cell will not produce a plaque and thus will not be counted. For example, a solution of tick-borne encephalitis virus with a concentration of 1,000 PFU/µl indicates that 1 µl of the solution contains enough virus particles to produce 1000 infectious plaques in a cell monolayer, but no inference can be made about the relationship of pfu to number of virus particles.

アルコールの量 unit
- 1unitの量が国によって違う。純エタノール換算で、1英unitは8g=10ml(英糖尿病協会採用の数値)、1米unitは15g(20ml弱:1drinkとも)で、日本では10~14g程度(代謝熱量80Kcalが基準:食品成分表5訂版,2002)や20ないし23g(日本酒1合分)を1unitとしている。日本の医学界では1unit=20g(体積に換算すると25ml)を採用することが多いので、ここでもそれに従う。この基準(1unit=20g=25ml)で計算すると、40度のウィスキー1ショット(=1オンス:英液量オンスで28.41ml、米液量オンスで29.57ml、日本の1ショットで30ml)が約0.5unitとなる。5度のビールなら500mlでだいたい1unit(この、日本酒1合≒ウィスキーダブル≒ビール500cc≒1unitという関係は、覚えておくと便利かもしれない:ワインなどは日本酒に準じるので、1本750mlがだいたい4unit強である)。 (参考1.より引用)
