1.5 Billion in Numbers
1.5 billion in numbers is 1,50,00,00,000.

Plain digits — no commas
How to write it
- Start from the unit itself. One billion is 1,000,000,000 — a 1 followed by 9 zeros.
- 1.5 billion means 1.5 × 1,000,000,000. Moving the decimal point 9 places to the right gives 1500000000.
- Now punctuate it. Indian grouping puts a comma three digits from the right and then one every two digits, giving 1,50,00,00,000. Forms, bank fields and spreadsheets that reject commas want the plain form above.
