Yeah it's a bit of a weird way the article puts it. Measuring in square meters but then referencing basket ball courts which are almost nonexistent in Europe :). They should have used a football (but soccer, not the American kind) field. Though in that case I guess it will be a fairly small division of one too which makes it sound smaller than it is.
I honestly have no idea how big a basketball court is.
I don't know where you are in Europe, but from my experience basketball is popular in France and courts are everywhere.
Soccer fields don't have a standard size, however, so you're not going to be able to give a true comparison.
Huh weird I've never seen one in Netherlands or Spain. In the Netherlands it's not popular at all though we have a similar thing that is ("korfbal").
My school did have these basketball boards but we never used them and I'm pretty sure the room was not sized for them either.
I'd love to say that my comment was some commentary on the weirdness of the units, but really, it just stuck out to me, and I thought it'd be funny if I treated "gridiron football field" as the imperial system equivalent unit to the metric "basketball court" unit.
I rarely make comments on HN that are mostly just humorous and not actually intending to be on-topic... but every once a year or so.
