The TIGER data base stores its latitude and longitude in decimal degrees

because it's easier for our internal operations.

Procedure for converting decimal degrees into Degrees, Minutes, Seconds:

Decimal degrees value: 37.427916

Step 1 Degrees = whole number part of decimal degrees

Degrees = 37

Step 2 Remove the whole number part of the decimal degrees number

37.427916 - 37 = .427916

Step 3 Multiply the remainder from step 2 by 60

.427916 * 60 = 25.67496

Step 4 Minutes = whole number part of results from step 3

Minutes = 25

Step 5 Remove the whole number part of the decimal number from step 3

25.67496 - 25 = .67496

Step 6 Multiply the remainder from step 5 by 60

.67496 * 60 = 40.4976

Step 7 Seconds = whole number part of results from step 6

Seconds = 40

Or if you want decimal seconds, then seconds = results from step 6

Seconds = 40.5

So decimal degrees 37.427916 = 37 Degrees, 25 Minutes, 40.5 Seconds.

Procedure for converting Degrees, Minutes, Seconds into decimal degrees:

Degrees, Minutes, Seconds value: 37 Degrees, 25 Minutes, 40.5 Seconds

Step 1. Decimal degrees = Degrees + (Minutes/60) + (Seconds/3600)

37 Degrees, 25 Minutes, 40.5 Seconds = 37. + (25/60) + (40.5/3600)

37. + .416666 + .01125

So 37 Degrees, 25 Minutes, 40.5 Seconds = 37.427916 in decimal

degrees.
