I am used to the decimal metric system for measuring the distances! In Great Britain there isn’t the metro and the kilometer as the unit length so when you drive through its roads and motorways, you must to learn all about miles, yards,… So let me begin:
1 mile = 1,609344 km = 1760 yards
1 yard = 0,9144 m.
In Continental Europe we are used to write 500 m in spite of 1/2 Km because the decimal system is very comfortable for us. In Britain, it’s better to say 1/4, 1/2 or 3/4 miles than 415, 830 or 1245 yards, respectively. Here we have a case in which fractions are very useful!
