The full quote in dirty imperial units:
I live my life a quarter mile at a time. Nothing else matters: not the mortgage, not the store, not my team and all their bullshit. For those ten seconds or less, I’m free.
– The Fast and the Furious
How was this translated to metric?
I think since it was a reference to a drag strip it was translated as a quarter of a mile everywhere else. At least where I live we use metric and we still call it eight mile, quarter mile and half mile when it comes to drag events
