Srimathe Ramanujaya Namah! Sri Sriranga Narayana Jeeyar Swamigale Saranam! 

Velukkudi Swamigal Thiruvadigale Saranam!

Recently I came to hear that 1 Yojanai = 8 miles and Surya Siddhanta says its 5 miles. However, as per Sri Vaisnava scriptures, our understanding is that 1 yojanai = 10 miles. Velukkudi Swamigal has also mentioned about this in many lectures. 

How do we support our stand with the reference to scriptures? 


Ramanuja Dasan!

Sri Ramanuja Munaye Namaha,

Sri Velukkudi Krishnan Swami Guruve Namaha,



Dear BhagavAta,


Based on Sri Velukkudi Swami’s Arul and Asmadh Acharyan’s Krupai and Google Acharyan’s support, here are some facts regarding 1 Yojana = how many miles.


Shastras DOESN’t use the British Imperial system of measurement units,

Like we use ‘Inches’, and British defined the inches as 1/12th of “A feet”, and that Feet is the length of Roman King foot. So, how to decide the length of Roman King’s foot, how long is his foot is?. So, British ‘BenchMarked” that Roman Kings’ feet as 1 Feet, then divided 1/12th of his feet as 1 inch and so on broke down to cm and mm.


Shastras smallest Unit is ‘Angulas”. The present day “inches” are termed based on this Angulas


1 Angula = Breadth of a Human Finger (Not the breadth of thumb)


Here is the General Formula as per Shastras for Angulas to Yojanai


1 angula = ‘X’ of present day inch;
4 angula-s = 1 dharnugraha [bow grip];
8 angula-s = 1 dhanurmuSTi [fist with thumb raised];
12 angula-s = 1 vitasta [span-distance of stretched out palm between the tips of a person’s thumb and little finger];
2 vitasta-s = 1 aratni / hasta;
4 aratni-s = 1 danDa / dhanus;
10 danDa-s = 1 rajju;
2 rajju-s = 1 paridesh;
2000 dhanus-s = 1 krosa / goruTa
4 krosa-s = 1 yojana


So, over all 768000 Angulas = 1 Yojanai.


Now, coming back to converting Angulas to inches, the length of a feet changes from yuga to yuga and even it redcues from century to century within the kali yuga. So , if we keep a 1 foot scale on our feet, our feet is samller than the actual 1 feet scale, so we can imagine, how much longer the Roman kings feet were in old days which matches the 1 feet scale.


Hence, during time to time, when Acharyas/Yuga Purushas calculate the “Angulas” to that present day Inches, the value of the “Conversion factor” keeps changing”, since they consider the AVERAGE feet length of humans in that period as 1FEET.


Ramanujar avataram period was 1017~1137 CE, and Britain/England was formed only recently around 1603, so Acharyas defintion as per Angulas = Breadth of a finger (other than Thumb).


Swami Ramanujar was 8 feet tall approx based on present calcualtions, we could imaging Swamis finger breadth, 1 Angula = 2.09cm (Its no wonder). So, based on the Shastras formula, 1 Yojana = 10miles. Present day Acharyas recently SriPerumputhur Swami in 1873 period made the Brahmamdam image, where Swami has mention 1 Yojana = 8 miles, which means 1 Angula = 1.68cm, which is approx same as present day humans finger breadth.


  • Sri Velukkudi Swami’s answer of 1 Yojana = 10 miles is based on Swami Ramanujar’s finger breadth of 1 Angula =2.09cm.


  • And later Acharyas/Maha Purushas after 1137CE (around 1800 CE) has defined as 1 Yojana = 8 miles, based on their period finger breadth of 1 Angula = 1.68cm.


  • There are also some conversions, where other Sanatana Dharma acharyas calculated 1 Yojana = 9 miles. Means their finger breadth of 1 Angula = 1.88cm.


  • In order to get 1 Yojana = 5miles as BhagavAta mentioned, the conversion should have been done in very recent times, where their finger breadth of 1 Angula = 1.05cm.


  • Literally, If we consider 1 Angula = 1 Inch (12.54cm), then 1 Yojana = 12.1miles.


Here is conversion factor of Inches based on the breadth of finger (1 Angula) measurements at  different periods.


if 1 angula = 0.41 inch = 1.05cm, then 1 yojana =5 miles         ==>
if 1 angula = 0.66 inch = 1.68cm, the 1 yojana =8 miles           ==>
if 1 angula = 0.74 inch = 1.88cm, the 1 yojana =9 miles           ==>
if 1 angula = 0.825 inch = 2.09 cm, the 1 yojana =10 miles   ==>
if 1 angula = 1 inch = 2.54 cm, the 1 yojana =12 miles              ==>


1 Yojana =

768000 Angulas

If 1 Angula =

below Inches

inch to miles conversion factor Miles
X Y Z X x Y x Z
768000 0.415 1.58E-05 5.0
768000 0.66 1.58E-05 8.0
768000 0.74 1.58E-05 9.0
768000 0.825 1.58E-05 10.0
768000 1 1.58E-05 12.1


If we need to get the actual definition of 1Feet and to know how much is it in present day inches, then we need to check on North Side, where there is SriRama’s SriPadha Impression in a rock, then we can divide BhagavAn’s feet length to 12 sections and that 1 section should be the actual 1 inch.


Then, we will get the actual value of 1 Yojana = how many miles.


Even the Distance of Braha loka (Sathya lokam) inside one Andam has a Measurement value in Yojanas as per Vishna Purana. However, adiyen personally believe, the Value of 1 yojana = 5 or 8 or 9 or 10 or 12 miles are immaterial for Prapannas, since our Destination SriVAikuntam is beyond any measurement, and the only route to Moksham SriVaikuntam is our Swami ramanujar ThiruvAdi and we ALL will travel through ArchaRaadhi maargam with Asmadh Acharya Krupai and Sri Velukkudi Swami’s Abhimaanam in this same janma.

I can only keep singing pallandu! Swami’s answer has made me speachless. Couldn’t have found a better explanation than this. Thank you Swami!

One request Swami:

We know your handle name. Can we get your initiated name? Hope it’s not offensive, if so pls forgive me.

Srimathe Ramanujaya Namaha,


Nandri Badri Swami for the Abhimaanam. All due to Acharya ThiruvAdi Bhalam and Velukkudi Swami’s Aasirvadham, Adiyen was able to pull/research details and solve this mystery of “Yojanai to Miles”.

For some reason, Adiyen missed the supplement post/request from devareer in the past, so Adiyen couldn’t answer earlier.


Regarding devareer’s request as “We know your handle name. Can we get your initiated name?

Ans: Adiyen’s “Initiated name (Acharya given name during Samasrayanam) is available in adiyen’s very FIRST post in dharma Sandeha on 26Oct’2016 as in below link, where Adiyen’s “Handle name and Initiated name are same as displayed”, and Adiyen also has been posting till date using that Initiated name as well in separate threads due to all BhagavAtas Abhimaanam……..😇🌷🙏




Adiyen Sri Velukkudi Krishna Dasan,

Uyya Oraey Vazhi UdayavAr ThiruvAdi,

Sarvam Sri Krishna Kudumbham.

Srimate Ramanujaye Namaha,

Nandri Elayalwaar swami (alias kongilpiratti swami) for clarifying that both the handles belong to you.

Wow, adiyen missed to notice this till date, very blessed to be associated with great Bhagavathaas under the shelter of Asmadh Acharyan and Sri Velukudi Swamigal 🙏

Badrinarayanan swamy, Elayalwar swamy has notified us only today..so it is not possible to notice it earlier..😊

Srimathe Ramanujaya Namaha,

Nandri BhagavAtas for the abhimaanam.

With Acharya ThiruvAdi Bhalam and Velukkudi Swami’s Aasirvadham, in addition to adiyen’s above post, adiyen has recently came across in one of the pravachanam that Sulba Sutras has another formula for 1 Angula.

1 Angula = length of 34 sesame seeds instead of using 1 Angula = thumb width (as posted above). Now don’t ask adiyen, what is the length of 1 sesame seed in olden time (Shastric way) compared to this yuga measured using British Imperial system……adiyen don’t know…..

Then the Angula to Yojana calculation is same as in the above post.

768000 Angulas = 1 Yojana.

Adiyen (ElayaAlwar) Srinivasa (DhoddayacharyAr) Dasan.
