CompareContrastConnect: Converting Decimal Degrees to Degrees, Minutes, and Seconds
Latitude and longitude coordinates can be written using degrees, minutes, and seconds or using decimal degrees. Location is given as decimal degrees in most GPS (Global Positioning System) units and on Google Maps. Both methods of writing location are correct.
1. To convert seconds to minutes, divide by 60  57 / 60 = 0.95 
2. Add your minutes together  0.95 + 43 = 43.95 
3. Divide your minutes by 60  43.95 / 60 = 0.7325 
4. Add to your degrees  0.7325 + 43 = 43.7325 decimal degrees N 
1. Subtract the whole number (this is the degrees)  = 49° and 0.947 as the decimal 
2. Multiply the decimal by 60 0.947 x 60  = 56.82 
3. Subtract the whole number (this is the minutes)  = 49° 56’ and 0.82 as the decimal 
4. Multiply the decimal by 60 0.82 x 60  = 49.2 
5. Subtract the whole number (this is the seconds)  = 49° 56’49” W 
 Lōʻihi seamount is the newest volcano in the Hawaiian chain (SF Fig. 1.14). The position of Lōʻihi’s northern cone is 18° 56′ 1′′ N, 155° 15′ 5′′ W. Convert this position into decimal degrees.
