>>16702921it actually refers to the common prefix kilo-, typically used to denote a multiple of a thousands of a unit
this would lead sone people to believe that the post you replied to means to say you weight 664 kilograms, as kilo- is a very common prefix in SI units; but since the post doesn't specify any kind of unit, we can assume it refers to thousands of the board's standard unit of weight (pounds, obviously)
in other words, you weight 332 tons, cripolebitch
