Scientific Notation Calculator
Scientific notation is a method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power. It is a form of presenting very large numbers or very small numbers in a simpler form.

How to Find Scientific Notation?
A scientific notation is a form of writing a given number, an equation, or an expression in a form that follows certain rules. Writing a large number like 15.5 billion in its number form is not easy but also time-consuming and there are chances that we may write a few zeros less or more while writing in the number form. So, to represent very large or very small numbers concisely, we use scientific notation. The general form of scientific notation is:
a × 10b ; 1 ≤ a < 10
Where 'a' represent any number between 0 to 10 ( greater than 0 and lesser than 10) and 'b' is any number.
Scientific notation rules:
To determine the power or exponent of 10, let us understand how many places we need to move the decimal point after the single-digit number.
- If the given number is multiples of 10 then the decimal point has to move to the left, and the power of 10 will be positive.
Example: 700 = 7 × 102 is in scientific notation.
- If the given number is smaller than 1, then the decimal point has to move to the right, so the power of 10 will be negative.
Example: 0.004 = 4 × 0.001 = 4 × 10-3 is in scientific notation.
Find scientific notation for 0.00748
Move the decimal point to the right of 0.00748 up to 5 places.
The decimal point was moved 5 places to the right to form the number 748
Therefore, the scientific notation for 0.00748 is 7.48 × 10-3
