A verse from RIGVEDA(I,50-4).
In the verse Sun light speed is referred with the help of units called YOJAN.
"Yojananam Dwe Dwe Shate Dwe Cha Yojane Aken Nimishardhena Krammana Namostute"
In this verse sun is referred to with respect saying that sunlight moves 2202 Yojans in Half Nimish. Yojan is quite a common unit in India. It means 4 KOSE, each kose measuring 8000 BRITISH YARDS AND EACH YARD MEASURING 0.9144 M.
The Definition of time unit Nimish can be found in ShrimadhBhagwat(ii,11-3 TO 10) WHERE IT IS MENTIONED THAT 15 NIMISHAS MAKE 1 Kashta,15 kashtas make 1 laghu, 30 laghus make 1 muhurtas and 30 muhurtas make 1 Diva-ratri. A diva Ratri is day-night and 24 hours in modern language. When you convert 2202 YOJANS PER HALF NIMISH INTO SI UNITS YOU FIND IT TURNS OUT TO BE:
3X10^8 m/s upto two significant digits a value quite accurate as we know it today
15 Nimish = 1 Kashth
30 Kashth = 1 Kaal ( 30 * 15 Nimish = 450 Nimish)
30 Kaal = 1 Muhurt ( 450 * 30 Nimish = 13500 Nimish)
30 Muhurt = 1 Ahoratr ( 13500 * 30 Nimish = 405000 Nimish)
1 Ahoratr = 1 Day (24 Hours)
1 Day = 24 * 60 * 60 Seconds = 86400 Seconds
86400 Seconds = 405000 Nimish
1 Second = 4.69 Nimish
1 Nimish = .214 Second
