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

Large mathematical number like 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 the example of conversion of small numbers into the standard form:

Number: 0.0000067833

How to write in 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.

decimal point step 2

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

decimal point step 3

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.

decimal point step 4

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

What is Standard Fraction?

The Standard Form of the fractions is known as the Standard Form. 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 e.g. 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
