The following calculators will convert latitude and longitude coordinates between three different unit types:

**Degrees/Minutes/Seconds**: DD MM SS (Ex = 39 54 32)**Decimal Degrees**: minutes and seconds are converted to decimal format. (Ex = 39.9088 degrees)**Degrees/Minutes**: seconds are converted to decimal format. (Ex= 39 degrees 54.5333 minutes)

Entering negative values of longitude are not necessary. For example, coordinates for Colorado can be expressed as 39deg, -108deg or 39 N, 108 W. The calculators assume positive numbers.
