Anyone willing to help me with compass rose

[Biegel86]

I have a heading of 50° 4.0
Also 200° 2.97 .
I'm familiar with the degrees but not with the decimal parts. Anyone willing to explain what the decimal parts mean. Thanks for any help I really appreciate it

It's broken down Degrees, minutes, seconds each degree can be broken down to 60 minutes and each minute down to 60 seconds.

30' = 1/2 degree

Looks like what you have written is taking a degree and dividing it by 100


To convert, you:

• Subtract the whole number - that is the degrees (12 degrees)
• Multiply the remainder (.3456) by 60 to find the minutes (20.736)
• Subtract the whole number - that is the minutes (20 minutes)
• Multiply the remainder (.736) by 60 to find the seconds (44.16 seconds)

Thank you very much

With the decimal, though, it is degrees, minutes and decimal of minutes. 4.0 would be 4 minutes and zero seconds. 2.97 would be 2 degrees and 58.2 seconds (not practical for following a course).

Though I have never heard of fractional headings. Locations and bearings, yes. Headings, no.

Are they headings and distances? 4.0 miles at 50°? (And remember a nautical mile is 6,000 feet).

They are random rocks that read exactly 50°4.0. The other rocks found which had the 200° 2.97 led me to a location to find the last rock with 50° 4.0 . But none of the decimal measurements were adding up for the distance . But they may mean nautical miles like you said so I'll run the formulas on that . Thanks I'll let you know what I find .

The decimal part of a degree is easy to change to minutes. A degree is 60 minutes. If you have, for instance, .50 degree, you have one half of a degree.... 30 minutes. Take the decimal part of a degree and multiply it into 60. Example..... 2.60 degrees is 2 plus .60 times 60 equals 2 degrees and 36 minutes or 2 degrees 36 minutes. This is also done to the minutes and seconds. Did this help? ╦╦Ç

without knowing important details like location of stones, distance and azimuth from each other its all guessing.

The first stone was found . It had IV 13° 4.64 on it . It led me to the next rock which was 13 ° 10 minute drive 5.9 mile drive. This rock had VIII 202° 2.97 which was 7 minute drive 3.7 mile drive . And that's the XII rock with 50° 4.0 but using regular miles it leads me nowhere, usingnautical miles it still leads me nowhere. Does this help any
