To convert a decimal number (dn) to degrees (d), minutes (m) and seconds (s):
d = int(dn) mi = frac(dn)*60 m = int(mi) s = frac(mi)*60

Note that int(n) denotes taking the integer part of a number (i.e. int(49.5125) = 49) and frac its fractional part (i.e. frac(49.5125) = 0.5125). mi is an intermediate result.

Example: To convert 49.5125 decimal degrees to degrees, minutes and seconds:

d = int(49.5125) = 49 mi = frac(49.5125)*60 = 0.5125*60 = 30.75 m = int(mi) = int(30.75) = 30 s = frac(mi)*60 = 0.75*60 = 45

Many calculators have a built-in function to compute this - it is often called "dms" or "hms". Switch to scientific mode on your calculator. To convert from decimal to degrees, minutes and seconds, enter the number, then hit the dms button.

To convert from degrees, minutes and seconds to decimal degrees, enter the degrees, a decimal point, then the minutes (2 digits) and seconds, then hit the [x]Inv (Inverse) button to get the inverse function and hit the dms button again.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or or How to display code and escape characters are good places to start.
