The Scillies are the most southerly point in the UK and have made a thing out of the latitude. However, they are only 5 minutes off being 50 degrees north of the Equator. So how far is 5 minutes? The radius of the Earth is 6371km so circumference = 40030km. That's 360 degrees so 1 degree is 111.2km. 1 minute is 111.2/60 = 1.853km. 5 minutes is 9.266km which is comfortably enough to take in Tresco and St Martins meaning all of Scilly must be below 50 degrees.
