In Hanuman Chalisa, it is said :
"Yug sahastra yojan per Bhanu!
Leelyo taahi madhur phal janu!!
Yug x Sahastra x Yojan = par Bhanu
Satya-Yuga 4,800
Treta-Yuga 3,600
Dvapara-Yuga 2,400
Kali-Yuga 1,200
the length is 4800 years + 3600 years + 2400 years + 1200 years for a total of 12,000 years for one arc.
युग x सहस्त्र= १२०००*१०००
1 योजन = 4 कोस = १२.५ Kms = approx 8 माइल्स.
युग x सहस्त्र x योजन=१२००००००*१२.५
युग x सहस्त्र x योजन = १५००००००० = १५० मिलियन किलोमीटर
