Chatank bhar ka hai tu....tere ko ratti bhar bhi akal nahi

Ever wondered what do chatank and ratti mean, used commonly in hindi. This is how old Indian measurement looks like:

1 mann = 37 kilo (approx)
1 mann = 40 ser
1 chatank = 5 tole
1 ser = 16 chatank
1 ser = 80 tole
1 tola = 12 maase
1 maasa = 8 ratti


a quick paheli:
ek mann ka ek lakkad
uspar baitha makkad
ek ek ratti roz khave

batao pura kitne din mein khayega?!
