In fact, he is wrong. According to "The International System of Units (SI)" 8th edtion, 2006, published by
Organisation Intergouvernementale de la Convention du Mètre, in other words, according to the official standard:

Unit symbols are mathematical entities and not abbreviations. Therefore, they are not followed by a period except at the end of a sentence, and one must neither use the plural nor mix unit symbols and unit names within one expression, since names are not mathematical entities.

So in official English, "kilometres" should always be written either as "kilometres", or "km", never as "kms".
