How many miles of coastline are there in the world?
The total length of the worlds coastline is in the region of 217,490 miles, or to put it another way, roughly equal to the distance from the Earth to the Moon. It is estimated that hundreds of kilometres of coastline are eroded globally each year which can either lengthen or shorten the total length of coastline making it impossible to be more accurate. The length of Britain’s coastline is about 9,040 miles. Of course this answer could be thrown to the dog’s if you were to use a much more accurate denomination of measurement such as meters. I shall explain… If you were to lay a one mile measuring stick along a length of coastline, and then measure the same length of coastline using a one meter measuring stick, you would undoubtedly record a greater distance by using the one meter stick as it could be used to get into all the nooks and cranny’s. So, the smaller your measuring stick, the greater the length you would record. With that in mind, another answer to your question would be ‘a
