1928 W. N. Shaw Man. Metereol. II. p. xxxii Kilobar, a name which it is proposed to substitute for the word ‘millibar’ to express a pressure of 1000 dynes per square centimetre, on the ground that the word ‘bar’ had been used in Physical Chemistry to denote the C.G.S. unit of pressure (1 dyne per square centimetre) before it was employed in meteorology to express a million dynes per square centimetre.

1968 Listener 27 June 828/1 This power package contained as its energy source 17 kilocuries of Plutonium 238.

1950 S. Glasstone Sourcebk. Atomic Energy iii. 82/1 One [sc. energy unit], equal to a thousand electron volts, called the kilo-electron volt, is represented by Kev.

1971 D. W. Sciama Mod. Cosmol. ii. 31 The distinction between X- and γ-rays is a somewhat arbitrary one, but..we may take the dividing line to be an energy of 100 keV (kilo-electron volts).
