俱舍論疏 11.30

11.30

論「其餘六海至二萬二千」，明餘六海及鹹海量。總略計九山及八海，一四天下徑總有一百二十萬八百七十五踰繕那。

The commentary says: "The remaining six seas... twenty-two thousand"—this explains the measurements of the remaining six seas and the saltwater ocean. Reckoning the nine mountains and eight seas as a whole, the total diameter of one set of four continents is one million, two hundred thousand, eight hundred and seventy-five yojanas.
