Decimal Degrees to D-M-S

201030Mar

I’m mainly putting this out there for my ref­er­ence in the future since I’m always for­get­ting this. Here’s how to con­vert Dec­i­mal Degrees to Degrees-Minutes-Seconds:

  1. Mul­ti­ply dec­i­mals (not whole num­ber) by 60. The whole num­ber remain­ing is your minute value.
  2. Now mul­ti­ply the minute value’s dec­i­mals by 60. The entire num­ber (includ­ing dec­i­mals) remain­ing is your sec­onds value.
    • Exam­ple: 12.9975°
    • 12° (0.9975 * 60)’ = 12° 59.85 = 12° 59′ (0.85 * 60)” = 12° 59′ 51″

Hope this comes in handy for some­one at some point.
