Enter Hex Here


There are different Hex To Decimal types of number systems, including binary, octal, decimal, hexadecimal, etc. Using certain rules of conversion, we can easily convert one base system to another. In this post, you’ll learn about hexadecimal and decimal systems, hex-to-decimal conversion, conversion charts, tables, and examples.

The system with Hexadecimal Numbers

The basis of the hexadecimal structure is 16. 10 decimal digits and the first six letters of the English alphabet are included in the 16 symbols used in this scheme, i.e. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. Alphabets of 10, 11, 12, 13, 14 and 15 can be handled here. Find out more here about the hexadecimal method.

A system with Decimal Number

A number system that uses digits from 0 to 9 to represent a base 10 number is called the system of decimal numbers. The number is expressed as base-10, were 0 or the first nine positive integers are used to denote each value. The place value of power 10 is given to each value in this number system. This indicates that the digit in the place of tens is ten times greater than the digit in the place of the unit.


First, in this tutorial, a decimal or hex bit reflects a single number, digit, or letter. A decimal, since it consists of ten numbers, is often called base 10 and denary. These are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, respectively.

A decimal is a system of numbers and can be represented by a subscript of 10 (i.e. 23510 reads as two hundred and thirty-five base 10).

In daily counting, decimals are the numbers we use. As we have ten fingers, we always use the decimal number system. A combination of two of these decimal numbers is used to create the numbers 10: 1 and 0, whereas a number like 209 is a combination of three decimal numbers: 2, 0, and 9.

There is no limit on how many times it is possible to reuse numbers, which is why it is often said that numbers never stop.


A hexadecimal is a representation of four binary bits and consists of sixteen numbers and letters, which is also called base 16 or’ hex’ for short. The hex numbers are equivalent to the decimal numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. the major distinction between a hex and a decimal is that letters are also found in a hex. The letters in question are A, B, C, D, E, and F.

It is possible to represent a hex number using a subscript of 16. These letters come in ascending order after decimals. The hexadecimal sequence, therefore, looks like this: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. A hex can be considered to be a shorter decimal version. For instance, using fewer hex bits to represent the decimal number, a large number in decimal form has a much smaller hex equivalent.

How to Convert Hexadecimal to Decimal

Hex is a number for base 16, and decimal is a number for base 10. We need to know each digit of the hex number’s decimal equivalent. To search the hex for a decimal table, see the page below.

The steps for converting the hex to decimal are as follows:

  1. Get the table’s decimal equivalent of a hex.
  2. Multiply every digit with 16-digit placement power.
  3. All the multipliers add up.

Hex to Decimal Conversions Process

The following example helps you to understand how to convert hex to decimal.

Example: The hexadecimal number 5AF (base 16) is converted to its corresponding decimal value.

You can write the hex number 5AF (base 16) as follows:

= 5 x 16^2 + A x 16^1 + F x 16^0

Replace the hexadecimal numbers with their corresponding decimal values and do the arithmetic operation.

A = 10 and F = 15;

= 5 x 16^2 + 10 x 16^1 + 15 x 16^0

= 1280 + 160 + 15 = 1455 + 15 = 1455

The equivalent of a decimal is 1455 (base 10)

How do you manually convert from Hex to Decimal?

To manually convert a hexadecimal to a decimal, you must begin by multiplying the number of a hex by 16. Then, according to the hexadecimal number equivalent, you lift it to a power of 0 and increase the power each time by 1.

When the powers are applied, we start from the right of the hexadecimal number and go to the left.

The power of 16 increases each time you multiply a number by 16.

Your job should look something like this when translating C9 hexadecimal into a decimal.

Example 1

9 = 9 * (16 ^ 0) = 9 (16 ^ 0)

C = 12 * (16 ^ 1) = 192 (16 ^ 1)

We add the outcomes, then.

192 + 9 = Decimal for 201 (base 10)


Next, all of our hex numbers were translated to their decimal counterparts. C equals decimal 12 and 9 equals decimal 9, respectively.

Then, starting from the last number in the question, we multiplied the numbers 12 and 9 with 16 and its power. Know your powers start at zero.

Our first multiplication had a power of 0 and a power of 1 was the second multiplication. It would have had a power of 2 if there had been a third.

The (^) symbol represents “raised to the power of.” Hence, the first words in brackets read, “16 to the power of 0.” This means that zero times have been multiplied by sixteen. All that has been lifted to the power of zero is 1. 9 were multiplied by one, thus.

The word read in the second bracket, “16 to the power of 1.” A number elevated to the power of one is equal to that number. 12 were then multiplied by 16. We got 192 when we multiplied them.

To get our decimal equivalent number, which was 201, we then added the results.

Example 2

We want to convert the hex to a decimal ABC in this case.

Note that the number 16 is raised to 0 for the right part of the question. The power 16 is boosted by one more than the previous bit as we pass through the numbers and letters. For instance, if we had a number with 22 in the leftmost bit, the power of 21 would be multiplied by 16.

C = 12 * (16 ^ 0) 12

B = 11 * (16 ^ 1) 17

A = 10 * (16 ^ 2) 2560

We add the outcomes, then.

2560 + 176 + 12 = Decimal 274810

Frequently Asked Questions (FAQs)

1. How do you perform the hexadecimal calculation?

The hex count is a lot like the decimal count, except that there are six more digits to deal with. “If a digit location becomes greater than “F,” you roll the location to “0” and raise the digit to the left by 1. And roll up to 2016 once you’ve hit 1F16, and hold the right-most digit churning from 0 to F.

2. What’s the hexadecimal value there?

The hexadecimal (also base 16 or hex) numeral system is a positional numeral system in mathematics and computing that represents numbers using the radix (base) of 16. The four bits (binary digits) represent each hexadecimal digit, also known as a nibble (or nibble), which is half a byte.

3. Where is the usage of hexadecimal?

Hex codes are used to simplify binary codes in many fields of computing. It is important to remember that hexadecimal is not used by computers – it’s being used by humans to simplify the binary form to a form that is easier to understand. For machine use, Hexadecimal is converted into binary.


This can at first seem complicated for others. But be assured that converting from a decimal to a hexadecimal and a hexadecimal to a decimal can be easily mastered with a little practice.

Even, before using the calculator, I highly suggest you learn how to convert these number systems manually. You won’t feel like you need to rely on a calculator that way.
