Yep! :)
100,000 = 1 Lakh
1,000,000 = 10 Lakh
10,000,000 = 1 Crore
Now the slangs: 1 lakh is also 1 peti (typically in Mumbai underworld)
1 crore is also 1 khoka … same in the Mumbai underworld. But both terms now is widely used in urban educated circles as “cool” .. like jailhouse fashion! ;)
Get it? :)
