Look up kilo-in Wiktionary, the free dictionary. Kilo (from the Greek ÏÎ¯Î»Î¹Î¿Î¹, literally a thousand) is a decimal unit prefix in the metric system denoting multiplication by one thousand. It has been used in the International System of Units where it has the unit symbol k, in lower case.t uses kilo as meaning 2 10 = 1024, because of the mathematical coincidence that 2 10 is approximately 10 3. The reason for this application is that binary values natively used in computing are base 2 and not the base 10 which is used for the SI prefixes.
