**[Note # of numbers,easiest way to determine witch format is used]

[1 #s ] * * Decimal Degrees (DegDec) 43.135933  -77.4442
Note : minutes and seconds as a decimal part of degrees.aka's   (DD) .   
Used by MS Streets and Trips
 
[2 #s ] * * Degrees  & Minutes (MinDec) N 43° 08.156 ,  W 077°  26.652                                                        
Note : the Minutes have decimal  for seconds
 
 [3  #s ]  * * Degrees, Minutes, Seconds (DMS) N 43 08 09  W 77 26 39
This format represents each component of a coordiante (degrees, minutes, seconds) as a separate number

 [ # ]  * * Universal Transverse Mercator (UTM)           18T E 301213  N 477810
Your will never use this as an individual but nice to know it exist,but UTM is a completely different  notation system 
[Does not use any form of degrees,minutes,seconds]

How to Convert Degrees  & Minutes  (MinDec) to Decimal Degrees (DD)                                                  
convert  (MinDec) [ N 43° 08.156 ,  W 077°  26.652]       to      (DegDec)    [43.135933  -77.4442] 
Remove the degree ,divide decimal min portion by 60,add the degree
=============================================================
How to Convert Decimal Degrees (DD)     to  Degrees  & Minutes  (MinDec)
Remove the whole degree ,multiply decimal degree portion time 60 [gives a  minute & decimal sec answer] , add the degree
Just multiply the decimal portion by 60. Example: 97.506355* = 97* (.506355 * 60 = 33.813)' Cool

How to Convert Decimal Degrees (DD) to Degrees-Minutes-Seconds (DMS)
Remove the whole degree[numbers to the left of the decimal]. 
Multiply decimal portion times 60 [whole number is minutes] .
Multiply decimal  portion time 60 [whole number is seconds]  
Using either method, the latitude/longitude DD coordinate 42.36824 = 42 22 06 in DMS 
==================================================================
Conversion from Degrees-Minutes-Seconds (DMS) to Decimal Degrees (DD) 
Decimal Degrees = Degrees + (Minutes/60) + (Seconds/3600)
Decimal Degrees = 46 + (10/60) + (28/3600)
Decimal Degrees = 46 + (0.1666667) + (0.0077778)
Decimal Degrees = 46.17444   = 46 degrees, 10 minutes, 28 seconds
