Speed conversions, done exactly
One international mile is exactly 1.609344 kilometres, so every figure below is that exact conversion rounded to one decimal place. Each page also shows what a compliant car speedometer is allowed to display at that true speed, which is usually a good deal more.
Working the other way round? The speedometer error calculator takes a true speed and shows the whole range a compliant dashboard may display.
