意味

Kilo; prefix meaning one thousand. Used as shorthand for kilogram or kilometre in everyday speech.

A loanword from French 'kilo' used as a prefix and standalone abbreviation. On its own, キロ usually means either kilogram (weight) or kilometre (distance), with context determining which. For clarity, キログラム and キロメートル can be used. Common in daily life: 体重は何キロ (how many kilos do you weigh?), 駅まで二キロ (two kilometres to the station).
