Haw. Rev. Stat. § 706-665

For purposes of sections 706-606.5, 706-620, and 706-662(1), a conviction of the commission of a crime in another jurisdiction shall constitute a previous conviction. Such conviction shall be deemed to have been of a felony if sentence of death or of imprisonment in excess of one year was authorized under the law of such other jurisdiction. Such a conviction shall be graded, for purposes of section 706-620 by comparing the maximum imprisonment authorized under the law of such other jurisdiction with the maximum imprisonment authorized for the relevant grade of felony.
