 Aug 07, 2013, 06:37 PM Registered User United States, NH, Epping Joined Jul 2011 206 Posts i dont think -14 is correct. this is what i have to do: /* Get your magnetic decliniation from here : http://magnetic-declination.com/ Convert the degree+minutes into decimal degree by ==> degree+minutes*(1/60) Note the sign on declination it could be negative or positive (WEST or EAST) */ does that site just give me what i need? i need someone familiar with this

So, based on the formula they give you it's 8 * (1/60) = 0.13333 Then -15 + 0.1333333 So yes you're at -14.8666, or -14.9 rounded to one decimal place

i read it as degrees + min then * (1/60)

so maybe -15+88(1/60)?

something like that?
