可以想成：汽車儀表板上那個一哩一哩往上跳的數字。那個累積的總數就是這個字的核心。從它可以問出好幾個很實際的問題：這台車一輩子跑了多遠、你這個月開了多遠、加一次油能跑多遠、公司要按哩數付你多少錢——最後再離開車子，變成「這件事你還能榨出多少用處」。From the picture
按哩數給的錢
把哩數換算成錢：你開自己的車辦公事，公司照跑的哩數補貼你。數字還是同一個，只是後面接上了金額。

Money paid to you for each mile you drive your own car for work.

完全離開車子：一台車還能跑多少哩，就像一件事還能帶給你多少用處。剩下的哩數變成剩下的價值。
