Scientific Notation Calculator
Convert any number to scientific notation, E notation, and standard form.
The decimal point moved 6 places to the left, so the exponent is 6.
Use this scientific notation calculator to convert any number into scientific notation, standard form, and E notation. Enter a decimal, whole number, or very small value to get the result instantly.
The tool shows the converted value and helps you understand how the decimal point moves to create the power of 10.

What Is Scientific Notation?
Scientific notation is a way to write very large or very small numbers in a shorter form.
A number in scientific notation is written like this:
a × 10ⁿ
The value of a must be at least 1 and less than 10.
The value of n shows how many places the decimal point moves.
Example:
45000 = 4.5 × 10⁴
Example:
0.00072 = 7.2 × 10⁻⁴
Scientific Notation Formula
Scientific notation uses this format:
a × 10ⁿ
a is the coefficient.
10 is the base.
n is the exponent.
The coefficient must be between 1 and 10.
Example of Scientific Notation
Number: 5600000
Scientific notation:
5.6 × 10⁶
E notation:
5.6e6
Standard form:
5,600,000
The decimal point moved 6 places to the left, so the exponent is positive 6.

The decimal point moved 6 places to the left, so the exponent is positive 6.
How to Convert a Number to Scientific Notation?
Step 1: Move the decimal point
Move it until only one non zero digit is on the left side.
Step 2: Count the places moved
This number becomes the exponent.
Step 3: Decide the sign of the exponent
If the decimal moves left, the exponent is positive.
If the decimal moves right, the exponent is negative.
Step 4: Write the final answer
Use the format a × 10ⁿ.
Example:
730000 = 7.3 × 10⁵
Converting Small Numbers to Scientific Notation
Small numbers use negative exponents.
Example:
0.00045 = 4.5 × 10⁻⁴
The decimal point moves 4 places to the right.
That is why the exponent is negative 4.
Converting Large Numbers to Scientific Notation
Large numbers use positive exponents.
Example:
9200000 = 9.2 × 10⁶
The decimal point moves 6 places to the left.
That is why the exponent is positive 6.
Scientific Notation vs E Notation
Scientific notation uses × 10 with an exponent.
Example:
6.2 × 10⁵
E notation uses e instead of × 10.
Example:
6.2e5
Both mean the same value. E notation is often used in calculators, spreadsheets, and programming.
Scientific Notation vs Standard Form
Scientific notation writes a number as a coefficient multiplied by a power of 10.
Standard form writes the full number.
Example:
3.4 × 10⁶ in standard form is 3,400,000.
Example:
8.1 × 10⁻³ in standard form is 0.0081.
Scientific Notation and Significant Figures
Scientific notation often keeps the important digits clear.
Example:
4.560 × 10³ has 4 significant figures.
The digits in the coefficient show the significant figures. This is useful in science, measurements, and engineering calculations.

Common Mistakes
Using the wrong exponent sign
Large numbers need a positive exponent. Small numbers need a negative exponent.
Leaving more than one digit before the decimal
Scientific notation should have only one non zero digit before the decimal point.
Forgetting that E notation means × 10
4.2e3 means 4.2 × 10³.
Removing important zeros
Zeros after a decimal can show significant figures.
