Decimal Degrees to Degrees, Minutes and Seconds Interconverter ENTER decimal Degrees.ddddd  or  Deg Min Sec.sssss For experimentation, an empty input will generate a randomized degrees value. -161.0361674405°  =  -161° 02' 10.20278580" ____________________________________________________________ The process of reducing decimal degrees to degrees, minutes and seconds of arc is illustrated below. AngDeg = -161.0361674405 degrees = abs(-161.0361674405) = 161.0361674405 NumSign = - deg = floor(degrees) = 161° minutes = 60*(degrees - deg) = 2.1700464300005 min = floor(minutes) = 02' seconds = 60*(minutes - min) = 10.202785800032 sec = 10.20278580" ____________________________________________________________ Collecting the (NumSign, deg, min, sec) values to construct a Deg° Min' Sec.ssss" string, rounded to 4 decimals gives -161.0361674405° = -161° 02' 10.20278580" ____________________________________________________________ Circular Trigonometric Functions for -161.0361674405° radians = -2.810611336629614763060249 sine = -0.324971239618671967123320 cosine = -0.945723899148532508542388 tangent = -0.343621684839787448666880 Jay Tanner - 2021 June 21 Monday at 10:54:14 AM GMT
