  • Multiply the remaining decimal by 60.
    0.742*60 = 44.52, so the whole number 44 equals minutes.
  • Multiply the remaining decimal by 60.
    0.52*60 = 31.2, so the whole number 31 equals seconds.
  • Decimal degrees 156.742 converts to 156 degrees, 44 minutes and 31 seconds, or 156° 44' 31".

Degrees minutes and seconds in a circle

Why multiply decimal degrees by 60 to get minutes and seconds?

Circles and spheres have 360 degrees in a complete rotation. One degree has 60 minutes and one minute has 60 seconds. If you have 91.456 degrees you can see that your measurement is 91 whole degress plus 0.456 of a degree.

To state the decimal 0.456 degrees in minutes multiply 0.456*60 to get 27.36 minutes. Now you have 27 whole minutes plus 0.36 of a minute.

To state the decimal 0.36 minutes seconds multiply 0.36*60 to get 21.6 seconds. Since your decimal 0.6 is greater than 0.5 you can round up to 22 seconds if you like.
