How big is 1 crore?
- In time. 1,00,00,000 seconds make 115 days, 17 hours, 46 minutes and 40 seconds. Counting aloud from 1 at one number a second, without a break, would take that long to reach 1 crore.

- In money. 1,00,00,000 paise are ₹100,000. 1,00,00,000 one-rupee coins are, of course, ₹1,00,00,000, written on a cheque as "Rupees One Crore Only".

Ten times more and ten times less
Ten times 1 crore is 10,00,00,000 (10 crore), which is 100 million. One tenth of it is 10,00,000 (10 lakh), which is 1 million. Each step adds or removes one zero.
Mistakes to avoid
- Count the zeros before you write: 1 crore has 7. One zero too many makes it ten times larger.
- Do not mix the comma styles in one number. Write 1,00,00,000 or 10,000,000.
- In words, the unit stays singular after a number: "1 crore", not "1 crores".
