Miles, and the speed limits among them

1 mi 1.6093 km

5 mi 8.0467 km

26 mi 42.1648 km

30 mi 48.2803 km

55 mi 88.5139 km

65 mi 104.6074 km

70 mi 112.6541 km

One mile is exactly 1.609344 kilometres. Multiply miles by 1.609344. The same factor converts speeds, so 30 mph is 48.3 km/h, 55 mph is 88.5 km/h and 70 mph is 112.7 km/h — which is why European limits sit at 50, 90 and 110 rather than at tidy conversions.

How to convert miles to kilometres

1 Type the distance, or the speed, in miles.

2 Read the kilometre figure. The same number works for km per hour.

3 Press ⇄ to convert kilometres back to miles.

Adding sixty per cent is the shortcut worth knowing: sixty miles plus sixty per cent gives 96, against a true 96.56. It is accurate to under one per cent all the way up, which is closer than a car speedometer is required to be.

Questions

Does this work for speeds as well as distances? −

Yes. Miles per hour and kilometres per hour share the same factor, so the conversion is identical — only the unit label changes.

Why is a mile 1,609 metres and not something round? +
