Numbers in Millions

1 thousand = 1,000. 1 lakh = 1,00,000 (1 hundred thousand). 10 lakh = 10,00,000 = 1 million. 1 crore = 1,00,00,000 = 10 million. Indian system: thousands, lakhs, crores. International system: thousands, millions, billions. India: 1,40,00,00,000 people = 1 billion 400 million = 140 crore. Both systems are valid — know both!
