This is not what you asked for but it handles conversions

latlongDecDeg = {40.624, 47.973};

latlongDMS = DMSList /@
  latlongDecDeg

{{40, 37, 26.4}, {47, 58, 22.8}}

(latlongString1 =
   DMSString[latlongDecDeg]) //
 FullForm

"40\[Degree]37'26.40000\"N 47\[Degree]58'22.80000\"E"

(latlongString2 =
   DMSString /@ latlongDecDeg) //
 FullForm

List["40\[Degree]37'26.40000\"","47\[Degree]58'22.80000\""]

latlongString2 ==
 DMSString /@ latlongDecDeg ==
 DMSString /@ latlongDMS

True

latlongDecDeg ==
 FromDMS /@ latlongDMS ==
 FromDMS[latlongString1] ==
 FromDMS /@ latlongString2

True

latlongDMS ==
 DMSList /@ latlongDecDeg ==
 DMSList[latlongString1] ==
 DMSList /@ latlongString2

True
