Yes, that is correct according to my calculations.

As far as "S 38 degrees 15 minutes E", that looks correct, too - if fact I thought I posted that, but guess I edited it out. It's the same as S38°15'E anyway, using words instead of symbols. But "S 38 degrees E 15 minutes" I don't think is in correct format. Glad I'm not the only one.

I converted to decimal (141.75°) mainly because FizzyCalc requires it.

Thanks for the responses everybody. This is not a cache, but a practice exersize a friend set up for me, so maybe he's not up on this as much as i think he is, lol. The calculations that sabby and bdad are coming up with is what I think I need to find whatever it is I'm looking for. I think my friend is trying to start me off with some practice on following a heading accurately. Maybe what I asked in the first post was not asked correctly by me. I was assuming that azmuth, bearing, and heading are all the same names for following an accurate straight line to a specific point. I was given a starting point (a red ribbon on a tree) and was supposed to follow the S38 degrees E 15 minutes heading and go 1550 feet to whatever is there to find. I appreciate all the comments and help very much.

Quadrant bearings do not use 0-360° as most of us are accustomed to. Instead, they specify up to 90° E or W of N or South. So, Northeast (45°) would be N45°E, and Southwest would be S45°W. N90°E and S90°E would both be East.

S 38 degrees E 15 minutes, if it were written the way I think would be correct (Anyone that knows different speak up!) would be S38°15'E. since there are 15 minutes in a degree, we could also say S38.25°E. If we take 180° (Which is south on a typical compass) and subtract 38.25, we get the azimuth we need for our compass bearing, or 141.75°.

Hopefully that helps if it is a quadrant bearing. If you need a visual, I can draw something up.

This could make a good article if I had time to do so....

I think I'm missing something here. If there are 15 minutes in a degree wouldn't that make the 15 minutes E another degree, and make the S38 actually S39?

or would it make it S37 degrees, I am so confused about this, sorry for not understanding.

Aha, you caught me on this one. there are 60 minutes in a degree, which makes 15 minutes 1/4 of that, or .25°. Sorry for that confusion.

I guess I need to write 100 times on the board

There are 60 seconds in a minute; There are 60 minutes in a degree; There are 360 degrees in a full circle.
There are 60 seconds in a minute; There are 60 minutes in a degree; There are 360 degrees in a full circle.
There are 60 seconds in a minute; There are 60 minutes in a degree; There are 360 degrees in a full circle.
