UMF to MGO ratings conversion

    By converting UMF to MGO or vice versa, you can easily compare different types of manuka honey.
    UMF vs MGO ratings compared


    UMF stands for Unique Manuka Factor. According to Unique Manuka Factor Honey Association that manages the UMF trademark, the quality of manuka can be determined by the presence of unique signature compounds such as Leptosperin, DHA and Methylglyoxal. The more the unique signature compounds, the better is the purity and quality of the manuka honey, and the higher will be the UMF rating of the manuka honey.


    The MGO grading system is managed by Manuka Health New Zealand Limited. It measures specifically the amount of Methylglyoxal (MGO) compound in manuka honey. The concept is similar to UMF grading. The higher the amount of Methylglyoxal in the manuka, the better is the purity and quality of the manuka.
