When something takes 1 hour and 30 minutes, you usually say it took you an hour and a half. But if something takes 1 hour and 23 minutes, you wouldn't say it took you 1.38 hours. It's the same with degrees. You can use decimal degrees, but sometimes it's clearer to use degrees with minutes and seconds. You can tell them apart by the symbols after the number:
 The degree symbol is
°
;  The symbol for minute is
'
; and  The symbol for second is
"
.
The DMS format is most common in geographic coordinate system. Go to the coordinates converter to learn more about this topic.
For now, let's find out how our DMS calculator does it!
How to convert degrees minutes seconds to decimal degrees?  degree converter formula
How many minutes are in a degree? Just like with hours, one degree is equal to sixty minutes. And one minute has sixty seconds, which means that one degree has three thousand six hundred seconds.

1° = 60'

1' = 60"

1° = 3600"
To convert DMS to decimal degrees all you need to do is use this formula:
Decimal degrees = Degrees + Minutes / 60 + Seconds / 3600
Where does this DMS to decimal degrees formula come from? As you now know, 1 degree has 60 minutes. That means that 1 minute is ^{1}/_{60} of a degree, and 1 second is equal to ^{1}/_{3600} of a degree.
Let's look at an example: Convert 67°48'23" to decimal degrees.
This angle has 67 degrees, 48 minutes, and 25 seconds, so input these values into their correct places:
Decimal degrees = 67° + 48'/60 + 25"/3600 = 67 + 0.8 + 0.00694 = 67.80694° ≈ 67.81°
Simple, right? If you don't want to do the calculation by hand, our degrees minutes seconds calculator will do it for you! And, if you need a more precise answer, the fraction to decimal converter might be your lifesaver!
Now, let's see how to convert decimal degrees to DMS.
Decimal degrees to DMS  step by step conversion
Converting decimal degrees to degrees with minutes and seconds is slightly more challenging. Let's take it one step at a time:
 First, take the whole number part  these are the degrees.
 Then, take what's left and multiply it by sixty. Again, take the whole number from that  these are the minutes.
 Lastly, multiply the rest, again, by sixty. The result is the number of seconds.
To make it easier to understand, let's look at an example. What is 47.392° in DMS?
 The integer part from 47.392° is 47, so
degrees = 47°
.  The decimal part:
0.392
multiplied by60
equals23.52
. Take the integer again minutes = 23'
.  Take the decimal part of step 2,
0.52
, and multiply it by60
. You will get the amount ofseconds = 31.2"
.
The degree in decimals  47.392°  is the same as 47°23'31.2".
Why are we multiplying by sixty? 47.392° is the same as 47 degrees and 0.392 of a degree. As you know, one degree equals 60 minutes. By multiplying the part of a degree by sixty, you get 23 minutes and 0.52 of a minute. One minute equals 60 seconds. So, when you multiply the part of a minute by sixty, you find the number of seconds.
