Converting to and from Standard Form
Here we will learn how to convert to and from standard form , including how to adjust numbers to write them in standard form notation.
There are also converting to and from standard form worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.
What is converting to and from standard form?
Converting to and from standard form is where we convert an ordinary number to a number written in standard form or scientific notation.
Standard form is a way of writing very large or very small numbers by comparing the powers of ten. Numbers in standard form are written in this format:
Where a is a number 1\leq{a}\lt10 and n is an integer.
Converting between ordinary numbers and numbers in standard form can help us to compare numbers and interpret answers given in standard form on a calculator. To do this we need to understand the place value of a number.
E.g. Let’s look at the number 350000 and place the digits in a place value table:
So 350000 written in standard form is:
How to convert ordinary numbers to standard form
In order to convert ordinary numbers to standard form:
- Identify the non-zero digits and write these as a decimal number which is \pmb{ 1\leq{x}\lt10} .
- In order to maintain the place value of the number, this decimal number needs to be multiplied by a power of ten.
Write the power of ten as an exponent.

Converting ordinary numbers to standard form examples
Example 1: writing numbers in standard form with positive powers.
Write this number in standard form:
The non-zero digits need to be written in decimal notation.
The number needs to lie between 1\leq{x}\lt10
So the number will begin as 4.8… .
2 You now need to maintain the value of the number by multiplying that decimal by a power of ten.
3 Write that power of ten as an exponent.
4 Write your number in standard form.
Example 2: writing numbers in standard form with positive powers
The number needs to lie between 1\leq{x}\lt10
So the number will begin as 5.42… .
You now need to maintain the value of the number by multiplying that decimal by a power of ten.
Write that power of ten as an exponent.
Write your number in standard form.
Example 3: converting a small number to standard form
Write 0.00081 in standard form.
Identify the non-zero digits and write these as a decimal number which is \pmb{1\leq{x}\lt10}.
This number will begin with 8.1...
Identify what power of ten the decimal needs to be multiplied by in order to preserve place value .
8.1 \div 10000 = 0.00081
Example 4: converting a small number to standard form
Write 0.00718 in standard form.
Identify the non-zero digits and write these as a decimal number which is \pmb{{1\leq{x}\lt10}.}
The number will begin with 7.18…
7.8 \div 1000 = 0.0078
How to convert standard form to ordinary numbers
In order to convert from standard form to ordinary numbers:
- Convert the power of ten to an ordinary number
- Multiply the decimal number by this power of ten
- Write your number as an ordinary number
Explain how to convert standard form to ordinary numbers
Converting standard form to ordinary numbers examples
Example 5: converting standard form to an ordinary number.
Write 6.2\times10^4 as an ordinary number.
Write the exponent as a power of ten.
Multiply the decimal number by that power of ten.
Write your answer as an ordinary number.
Example 6: converting standard form to an ordinary number
Write 1.9\times10^{-3} as an ordinary number.
How to adjust numbers to standard form
Sometimes we might have a number that looks like it is in standard form however the decimal number is not between 1 and 10 , E.g. 36103 or 0.2104 . In this case we need to adjust the number.
In order to adjust numbers to standard form:
- Identify what power of ten the decimal number needs to be multiplied by so that the value is \pmb{1\leq{x}\lt10}.
- Apply the inverse of this to the power of ten.
Adjusting numbers to standard form examples
Example 7: adjusting number in standard form.
Write 48\times10^5 in standard form.
Identify what the first number needs to be multiplied or divided by so that it lies between \pmb{1\leq{x}\lt10}.
48 needs to be divided by 10 so 48 becomes 4.8 .
Apply the inverse operation to the power of ten.
10^5 needs to be multiplied by 10 which adds one to its power, so it becomes 10^6 .
Write your number in standard form.
Example 8: adjusting numbers to standard form
Write 0.68\times10^{4} in standard form.
0.68 needs to be multiplied by 10 so it becomes 6.8 .
10^4 needs to be divided by 10 which subtracts one from its power, so it becomes 10^3 .
Example 9: adjusting numbers to standard form
Write 290\times10^{-4} in standard form.
290 needs to be divided by 100 so it becomes 2.9 .
10^{-4} needs to be multiplied by 100 which adds two to its power, so it becomes 10^{-2} .
Common misconceptions
- Writing a number with the incorrect power for a large or small number
This error is often made by counting the zeros following the first non zero digit for large numbers or zeros after the decimal point for small numbers, then writing this as the power, rather than considering the place value of the given number.
- Identifying incorrect place value with small numbers
In a number such as 0.000682 , selecting the ‘2’ to determine the exponent rather than the ‘6’ which has a higher place value. In standard form, this number would be 6.82 × 10^{-4} .
- Errors with negative numbers
When checking the standard form of a number, incorrectly adjusting the negative powers due to not applying negative numbers rules correctly. E.g. With small numbers, adding one to the power of 10^{-5} will result in 10^{-4} not 10^{-6} .

Practice standard form calculator questions
1. Write 270000 in standard form
The number between 1 and 10 here is 2.7.
2. Write 0.00079 in standard form
The number between 1 and 10 here is 7.9.
3. Write 6.1 \times 10^{4} as an ordinary number
4. Write 3.8 \times 10^{-5} as an ordinary number
5. Write 84\times10^{2} in standard form
This number is not in standard form as 84 is not between 1 and 10.
We need to divide 84 by 10 and, to compensate, multiply 10^2 by 10 , increasing the power by 1.
This gives us
6. Write 0.92\times10^{-5} in standard form
This number is not in standard form because 0.92 is not between 1 and 10.
We need to multiply 0.92 by 10 and, to compensate, divide 10^{-5} by 10 , decreasing the power by 1.

Standard Form
What is "Standard Form"?
that depends on what you are dealing with!
I have gathered some common "Standard Form"s here for you..
Note: Standard Form is not the "correct form", just a handy agreed-upon style. You may find some other form to be more useful.
Standard Form of a Decimal Number
In Britain this is another name for Scientific Notation , where you write down a number this way:
In other countries it means "not in expanded form" (see Composing and Decomposing Numbers ):
561 | 500 + 60 + 1 |
Standard Form of an Equation
The "Standard Form" of an equation is:
(some expression) = 0
In other words, "= 0" is on the right, and everything else is on the left.
Example: Put x 2 = 7 into Standard Form
x 2 − 7 = 0
Standard Form of a Polynomial
The "Standard Form" for writing down a polynomial is to put the terms with the highest degree first (like the "2" in x 2 if there is one variable).
Example: Put this in Standard Form:
3 x 2 − 7 + 4 x 3 + x 6.
The highest degree is 6, so that goes first, then 3, 2 and then the constant last:
x 6 + 4 x 3 + 3 x 2 − 7
Also, within each term, it is nice to have the variables in alphabetical order (if it does not make things more confusing):
yzx 2 + 4 yx 3
The highest degree is 3, so that goes first, also put the variables in alphabetical order
4 x 3 y + 3 x 2 yz
Standard Form of a Linear Equation
The "Standard Form" for writing down a Linear Equation is
Ax + By = C
A shouldn't be negative, A and B shouldn't both be zero, and A , B and C should be integers.
Bring 3x to the left:
−3x + y = 2
Multiply all by −1:
3x − y = −2
Note: A = 3, B = −1, C = −2
Ax + By + C = 0
is sometimes called "Standard Form", but is more properly called the "General Form".
Standard Form of a Quadratic Equation
The "Standard Form" for writing down a Quadratic Equation is
( a not equal to zero)
Expand "x(x−1)":
x 2 − x = 3
Bring 3 to left:
x 2 − x − 3 = 0
Note: a = 1, b = −1, c = −3
Standard Form of a Circle Equation
With a circle like this:
The Standard Form is this:
(x−a) 2 + (y−b) 2 = r 2
See Circle Equations for more details.
