The present invention relates to a device for converting a blasting pattern coordinate and providing same, and a method therefor. The device comprises: a distance difference calculating unit for configuring, as a reference point, one of detonator holes displayed in blasting pattern coordinates which are designed by a blasting management program, and calculating a distance difference between the X and Y coordinates of the detonator hole configured as a reference point and those of each of remaining detonator holes; a polar coordinate value deriving unit for deriving polar coordinate values of the remaining detonator holes by designating, as a reference point of a polar coordinate, the detonator hole configured as a reference point; a relative angle deriving unit for deriving a relative angle between a first detonator hole and a second detonator hole; and a latitude/longitude value deriving unit for revising angles of the remaining detonator holes by reflecting the derived relative angle between the first detonator hole and the second detonator hole, and deriving latitude/longitude coordinate values of the detonator holes.
