Two lines of the Hindu prayer Hanuman Chalisa compute this distance with great simplicity.
जुग सहस्त्र योजन पर भानु, लील्यो ताहिमधुर फल जानू
1 yuga = 12000 celestial years
1 sahastra = 1000
1 yojana = 8 Miles
yuga x sahastra x yojana = para bhanu
12,000 x 1000 x 8 miles = 96,000,000 miles
1 mile = 1.6kms
96,000,000 x 1.6kms = 153,600,000 kms to the Sun.
