What is the standard form?

Standard Form is a term in mathematics that is used for converting long or complex numbers into the simplest form for reducing the difficulty to read the number.

It is a way to express very small or very long numbers.


The scientific notation calculator can be used for converting complex numbers into a readable format.

A large mathematical number like the given below is difficult to read. But, after it is converted into the standard form, it becomes easier to read.

Number: 5630000000000

Standard Form: 5.63 x 1012

Here is an example of the conversion of small numbers into the standard form:

Number: 0.0000067833

Standard Form: 6.7833-6

How to write in the standard form manually?

Below, we have explained the step-by-step conversion of a number into the standard format.


Convert 0.000381 to standard form.


Step 1: Write down the number.


Step 2: Find the decimal point in the number and if the decimal point is not there then it would be declared at the end of the number, on the right side.

Step 3: Place the decimal after the first non-zero digit and remove any leading or trailing zeros. In this case:

The number becomes,

Step 4: Now, count the number of positions you have changed for the decimal. Raise the total number of positions moved, to the power of 10. In this case, we have moved the decimal to 4 positions.

Keynote: If the decimal is moved from left to right, place the negative sign with the exponent. If the decimal is moved from right to left, raise the power as a positive integer


0.000381 = 3.81 × 10-4

What is Standard Fraction?

The Standard Form of the fractions is known as the Standard Fraction. When the numerator and denominator are co-prime then it is considered to be written in the standard form. But for this, both the numbers shouldn’t have a common factor of 1 For example. 5/6, 11/12.

What is the standard form of the quadratic function?

The general way of writing the quadratic function is:

f(x) = ax2 + bx + c

In Standard form, it is written as:

f(x) = a(x-h)2 + k
