The exact equation of compactness of sea ice is derived from the two-phase flow theory. The equation is compared with other approximate equations of compactness of sea ice in the literature and the improvement on the understanding of compactness effect is shown. The semi-empirical formula obtained by using simplified solutions of Fel'zenbaum (1958), while agreeing well with the empirical formula for wind drift of ice, shows the effects of compactness as well.
