The kos is an ancient unit of distance that has been in use in the Indian subcontinent for over three thousand years; evidence exists from Vedic times to the Mughal period, and even now elderly people in rural areas refer to distances from nearby areas in kos. A kos is about 2.25 miles. It is variously spelled "Kos", "Kosh", "Krosh", and "Koss" when rendered in the Latin alphabet. The ''Arthashastra'' gives this breakup of Indian units of length:〔 (【引用サイトリンク】accessdate=2007-09-29 )〕 * 1 Angul (approximate width of a finger) = approx. 3/4 of an inch; * 4 Angul = Dharnugrah (bow grip) = 3 in; * 8 Angul = 1 Dhanurmushti (fist with thumb raised) = 6 in; * 12 Angul = 1 Vitastaa (span-distance of stretched out palm between the tips of a person's thumb and the little finger) = 9 in; * 2 Vitastaa (from the tip of the elbow to the tip of the middle finger) = 1 Aratni or Hast (cubit or Haath) = 18 in; * 4 Aratni (Haath) = 1 Dand or Dhanush (bow) = 6 ft; * 10 Dand = 1 Rajju = 60 ft; * 2 Rajju = 1 Paridesh = 120 ft; * 2000 Dand (Dhanush) = 1 Krosh or Gorut = 4000 yards or 2 miles - nearly 3.66 km; * 4 Krosh = 1 Yojan = 9 miles - nearly 15 km; Kos may also refer to about 1.8 km (1⅛ mile) or 3.2 km (2 miles).〔''Measure for Measure'', Young & Glover, 1996〕 Along India's old highways, particularly the Grand Trunk Road, one still finds ''Kos Minar'', or mile markers, erected at distances of a little over two miles ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kos (unit)」の詳細全文を読む スポンサード リンク
