:  因為 1 升 ( L ) = 1,000 毫升 ( mL ) 

       1,000毫升       毫升
  即 1 = ─────── = 1,000 ────
        1 升         升

                   毫升
  所以  2.5 升 = 2.5 升 × 1,000 ────
                   升

                       毫升
          = ( 2.5 × 1,000 ) × 升 × ────
                       升

          = 2,500 毫升 ( mL )

  答案: 2.5 升 ( L ) = 2,500 毫升 ( mL )
