• 10^6 — Scientific notation (10 raised to the 6th power)

3. Practical Applications

Details: Understanding millions is essential in fields like economics (budgets), demographics (city populations), and science (molecular counts).

4. Conversion Examples

Examples:

• 2 million = 2 × 10^6
• 0.5 million = 5 × 10^5
• 10 million = 10^7

5. Frequently Asked Questions (FAQ)
