80 million in scientific notation is 8.0 × 107.
To convert 80 million to scientific notation, you express the number as a product of a number between 1 and 10 multiplied by a power of ten. Since 80 million equals 80,000,000, it can be written as 8.0 multiplied by 10 raised to the 7th power.

Conversion Formula
To convert a value given in millions to scientific notation, multiply the number by 1,000,000 (which is 106), then express the result as a number between 1 and 10 multiplied by 10 raised to a power.
For example, 80 million means 80 × 1,000,000 = 80,000,000. To write this in scientific notation:
- Find a number between 1 and 10 by moving the decimal point in 80,000,000: 8.0
- Count how many places the decimal point has moved from the original number: 7 places
- Write the number as 8.0 × 107
This works because multiplying by 107 means shifting the decimal 7 places to the right, which recreates the original number.
Conversion Example
- Example: 45 million
- Start with 45 million = 45 × 1,000,000 = 45,000,000
- Move decimal to get a number between 1 and 10: 4.5
- Decimal moves 7 places right, so exponent is 7
- Scientific notation: 4.5 × 107
- Example: 92 million
- 92 × 1,000,000 = 92,000,000
- Number between 1 and 10: 9.2
- Decimal moved 7 places, exponent 7
- Scientific notation: 9.2 × 107
- Example: 60 million
- 60 × 1,000,000 = 60,000,000
- Number between 1 and 10: 6.0
- Decimal moved 7 places, exponent 7
- Scientific notation: 6.0 × 107

Conversion Definitions
Million: A million is a number equal to one thousand thousands, written as 1,000,000. It’s a large numerical value commonly used in counting population, money, or quantities, and is expressed with six zeros following the digit 1.
Scientific: Scientific notation is a method of expressing very large or very small numbers by using a decimal number between 1 and 10 multiplied by a power of ten. It simplifies numbers and makes calculations easier in science and engineering.
Conversion FAQs
Why does 80 million equal 8.0 times 10 to the 7th power?
Because 80 million is 80,000,000, moving decimal point left 7 times converts it to 8.0, so we multiply by 107 to return to its original value. This is the basic rule for scientific notation where the exponent shows how many places decimal moved.
Can I write 80 million as 80 × 10 to the 6th power instead?
Yes, mathematically 80 × 106 equals 80 million, but scientific notation requires the first number between 1 and 10, so 8.0 × 107 is the proper form.
How does the conversion help in real-world calculations?
Using scientific notation simplifies handling very large numbers, making addition, multiplication, or division easier, specially in fields like physics or finance where large values like millions are common.
What happens if I convert a decimal million value, like 0.8 million?
0.8 million equals 800,000, which in scientific notation is 8.0 × 105. The exponent changes based on the position of the decimal point after converting to the full number.
Is the conversion formula same for billion or thousand?
While similar in concept, billion is multiplied by 109 and thousand by 103, so the exponent in scientific notation changes accordingly to reflect the scale of the number.
