Miles are funny things

• 1 Old English mile 2.1 km
• 1 Roman mile estimated at 1479 m
• 1 Statute mile 1.609 km
• 1 Nautical mile 1853 m
• 1 Scandinavian mile 10 km
• 1 Geographical mile 7.4 km
• 1 Metric mile 1500 m
• 1 Irish mile 2.048 km

We talk about

• milestones in a life
• a mile a minute
• going the extra mile
• walking a mile in someone else’s shoes
• a miss is as good as a mile
• run a mile
• give someone an inch and they will take a mile

….yet only three countries in the world don’t use the metric system: the United States, Liberia, and Myanmar.
