There is word that Oxford University is considering phasing out imperial measurements as part of its efforts to decolonise its maths, physics and life sciences faculties. So should I respond by decolonising my underpants drawer? A quick recce shows measurements in both inches and centimetres. Is that acceptable? Possibly not - every time I put on a pair of pants I might feel drawn to observe the inches measurements and lapse into a regression that would count as minor thought crime.
