Updated the coordinates.
Enjoy the waterfront and be careful of muggles.
As a SAR (search and rescue) volunteer I like learning new skills, so I've added a lesson on GPS conversions.
If you truly want the coordinate conversions there are plenty of them out on the net. But there are a couple simple rules that if you remember, are not difficult to master when no internet connection is available. Namely, minutes, in multiples of 60 (60 minutes in an hour and 60 seconds in a minute), get converted to a decimal number which is based on a multiple of 10 or 100. It's the same type of conversion as saying that a movie lasts two hours and 10 minutes (2:10) or 130 (130) minutes long. Or 15 minutes is a quarter of an hour (25% or .25). Not exactly the same but you get the idea.
In all examples, use the normal rounding rules. Also, the minus sign is assumed in front of the Longitude number.

Convert From: Degrees, Minutes, Seconds
Convert To: Degrees, Decimal Degrees
---------------------------------------------------------------------------------
Looking at the example below, for Latitude, start with the exact same degrees (37°) and whole number minutes (25), then take the seconds and divide by 60 (19.82 / 60 = .330). For Longitude, keep 122 and 5. Convert seconds 2.34 (2.34 / 60 = .039)
Example:
37°25'19.82"N, 122° 5'2.34"W (Degrees, Minutes, Seconds)
37° 25.330'N, 122° 5.039'W (Degrees, Decimal Minutes)
---------------------------------------------------------------------------------
Convert From: Degrees, Decimal minutes
Convert To: Degrees, Minutes, Seconds
---------------------------------------------------------------------------------
Looking at the example below, for Latitude start with the exact same degrees (37°) and whole number minutes (25), Then take the next numbers after and including the decimal and multiply by 60 (.330 x 60 = 19.. For Longitude, keep 122 and 5. Convert .039 (.039 x 60 = 2.34) Note: The numbers are vy close but may not be exactly the same. In this case 19.8 is very close to the actual 19.82, a difference of inches on the ground.
Example:
37° 25.330'N, 122° 5.039'W (Degrees, Decimal Minutes)
37°25'19.82"N, 122° 5'2.34"W (Degrees, Minutes, Seconds)
---------------------------------------------------------------------------------
Convert From: Decimal Degrees or standard Latitude, Longitude
Convert To: Degrees, Decimal Minutes
---------------------------------------------------------------------------------
Looking at the example below, for longitude, start with the exact same degrees (37°). Then take the next numbers after and including the decimal and multiply by 60 (.422172 x 60 = 25.330). For Longitude, keep 122 then convert .083983 (.083983 x 60 = 5.039)
Example:
37.422172°, -122.083983° (Decimal Degrees or standard Latitude, Longitude)
37° 25.330'N, 122° 5.039'W (Degrees, Decimal Minutes)

Convert From: Degrees, Decimal Minutes
Convert To: Decimal Degrees or standard Latitude, Longitude
---------------------------------------------------------------------------------
Looking at the example below, for longitude, start with the exact same degrees (37°). Then take the next numbers after and including the decimal and divide by 60 to 6 digits (25.330 / 60 = .422167). For Longitude, keep 122 then convert 5.039 (5.039 / 60 = .083983) Note: The numbers are very close but may not be exactly the same A difference of a few inches on the ground.
Example:
37° 25.330'N, 122° 5.039'W (Degrees, Decimal Minutes)
37.422172°, -122.083983° (Decimal Degrees or standard Latitude, Longitude)
---------------------------------------------------------------------------------
Convert From: Decimal Degrees or standard Latitude, Longitude
Convert To: Degrees, Minutes, Seconds
---------------------------------------------------------------------------------
This is a two step process.
1. First convert from Decimal Degrees to Degrees, Decimal Minutes.
2. Then convert the resulting number from Degrees, Decimal Minutes to Degrees, Minutes, Seconds.
---------------------------------------------------------------------------------
Convert From: Degrees, Minutes, Seconds
Convert To: Decimal Degrees or standard Latitude, Longitude
---------------------------------------------------------------------------------
The reverse is also a two step process.
1. First convert from Degrees, Minutes, Seconds to Degrees, Decimal Minutes.
2. Then convert the resulting number from Degrees, Decimal Minutes to Decimal Degrees.
