i didn't know that 'three kilos' are the same as 'three pounds?. never too late! percebe 1950
In the Netherlands a pound is legally the same as 1 kg, but only legally... in common parlance, insofar as you can say that for a word that's on the verge becoming extinct except in set phrases, a pound is ½ kg just like everywhere else.
So I guess I'll report that the official translation is wrong.
