What's the point?

The view from my building at work
Got asked an interesting question.  In a GPS longitude/latitude  measurement, how much resolution does each decimal give us?


Since each line of longitude is 68.71 Miles then
  • each tenth represents 6.9 miles (or 36,279 feet)
  • each hundredth represents .69 miles (or 36279 feet)
  • each thousandths represents 362 feet (or .07 miles)
  • each then thousandth represents 36.3 feet (or .0069 miles)
