    1 carat = 200 mg = 0.2 grams = 0.002 points. In the old gem book, one carat is about 205.3 mg. If it is converted to the current carat, one carat must multiply 1.0265, but it is just a rough saying, because the carat values ​​in the old countries or regions are different.
    The public carat unit, that is, one carat is equal to 200 mg and was adopted since 1907. Before that, one carat was equal to 205.3 mg, which is 0.2053 grams.
