Lennie,
6080 feet is the United Kingdom Nautical Mile
6076.115 feet is the United States Nautical Mile
According to the conversion program I use (Prokon, by Harold

So change the last two digits to correct it. Then try to read that

Sometimes factors applied with my old Post Versalog. Close enough for
most matters, except for nitpickers.
