Need to get some numbers handy

"India will soon become a $3 trillion dollar economy" "India's export crosses Rs.20 lakh crore" "Market valuation of ABC company to become Rs.1 lakh crore!" I always read these numbers in news and these made least sense to me. I had no idea how large or small these numbers were compared to other countries'/companies'. That is why here I have compiled important GDP numbers and other data to better compare the performance of countries and market opportunities of the businesses.
