how do i change language in youtube website?

At the very bottom left of virtually every YouTube page is

Current Location: ???????? Show locations

Current Language: ??????? Show languages

If you click on the blue "Show languages", you'll see the

19 different languages which YouTube is available in. All

you need to do is click on your language preference, but....

If everything you see is in Hindi, then you probably won't

see the 2 options which I wrote at the top of this answer

because they are most likely in Hindi. Therefore, search

for this at the very bottom of a YouTube page, then click

the last blue link that'll be on the left side:

वर्तमान स्थान: दुनियाभर में स्थान दिखाएं

वर्तमान भाषा: हिन्दी भाषाएं दिखाएं

below youtube.com site there is a option below bottom left corner "current language". it ll shows your current lang and also option to show all lang. so u can change it.

go to account settings.

It will work.
