It is very interesting for me, is the transmission of incorrect information - is it an inability to use the Internet or a conscious desire to distort the facts? (I am writing in advance for moderators that there are no insults in my words. This is a rhetorical question posed to the infinity of internet space
)
I do not dispute the fact that in some countries, the kentar could be 100 kg. But Afanasy Nikitin was a Russian and used the Russian measures of weight, recognised at the time.
Kentar is a Russian measure of mass, weight, introduced in the 15th century. In the 15-17 centuries, Kontar was equal to 2.5 pounds or 40.95 kg.
100 kg and 41 kg is a noticeable difference.
