DEF

Préfixe qui multiplie par 1000 l'unité qu'il précède.

OBS

kilo- : Élément du grec signifiant «mille». Symbole : k (sans point). Sa notation scientifique est 10³. [Ce] préfixe sert à la composition du multiple décimal et se juxtapose immédiatement au symbole de l'unité.

OBS

On peut écrire cinquante mille dollars comme suit : 50 000 $, 50 kilodollars, 50 k$.

OBS

Le «Multidictionnaire de la langue française» de Marie-Éva de Villers donne «k $» comme abréviation de «kilodollar», mais il faut plutôt écrire «k$» (sans espace).

OBS

Dans le SI, le symbole «k» est toujours une lettre minuscule; en informatique, on n'obéit pas nécessairement à cette règle.

PHR
