Hexadecimal to Decimal Converter

This tool is used to convert hexadecimal to decimal or decimal to hexadecimal.


What is a Hexadecimal?

Hexadecimal is a base 16 number system. Its biggest feature is that it consists of 16 unique symbols. The numbers 0-1-2-3-4-5-6-7-8-9 and the letters A, B, C, D, E, F form these symbols. Hexadecimal, which is similar to the Decimal or decimal number system that we use in our daily life, is a number system that is often used in the fields of information technology. Have you ever noticed that most of the error codes used in computers appear in hexadecimal form? Error codes, status codes, stop errors, and blue screen errors are constantly displayed by error codes from the hexadecimal unit. This is because computer programmers program error codes to be hexadecimal. Hexadecimal data is written shorter than the value it represents. So in a few numbers, they can actually convey a much deeper message to us. Computer programmers use hexadecimal because hexadecimal is shorter when compared to Binary or Decimal. Let's explain with a simple example; A hexadecimal value of F4240 can be written as 1,000,000 decimal and Binary code as 1111 0100 0010 0100 0000. Therefore, hexadecimal data can present the value it represents to us, even though it is written shorter. Another area where hexadecimal is widely used is in HTML color codes, which help symbolize exactly one color. A web designer will render the color red with the hexadecimal code FF0000. This code is parsed as FF,00.00 and each digit represents how much red, green and blue colors will be used. Hexadecimal values ​​can fit up to 255 values ​​into two digits of data. Since HTML color codes consist of three sets of values, it is possible to easily express over 16 million color ranges using HEX (255 x 255 x 255). Considering number systems such as decimal, hexadecimal offers us the advantage of time, size and space in this respect. Although the binary code system is easier to use in many ways, hexadecimal values ​​can be easily read and understood by humans. Calculating in hexadecimal format is fairly easy as long as you remember that there are 16 characters that make up each set of numbers. You know that counting in decimal form is done like this: 0,1,2,3,4,5,6,7,8,9,10,11,12,13, ... we continue again by adding 1 (i.e. the number 10) before starting the set of 10 numbers again. In hexadecimal, we need to include all 16 digits in the same counting method. This time we need to count the numbers in hexadecimal units like this: 0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F, 10,11,12,13 ... 16 by adding 1 before starting the set again The number is repeated again and again. Practicing with some trick passes that we believe you will find helpful can help you understand hexadecimal more easily:

Hexadecimal to Decimal & Decimal to Hexadecimal

Decimal is the decimal number system used in the computer content system. Using Decimal, any content can be encoded according to the decimal system and this coding can be read and understood by humans. Those who will work in the field of computer science should have a good grasp of the relationship of Decimal with Binary, Octal and hexadecimal in terms of understanding the logic. In the decimal number system, the digits 0-1-2-3-4-5-6-7-8-9 are used, unlike the 0 and 1 used in Binary. Since the sum of the digits used, including 0, consists of 10, this system is called the decimal number system. Although most modern computers count Binary, there are still computers that work by counting Decimal (Decimal Computers). Charles Babbage's Analytical Engine was designed using the decimal system. ENIAC and IBM 650, which we can accept from the first computer examples, also use the decimal number system. The decimal number system in mathematics is as old as humanity. According to rumors, the reason why this system has a 10-computing model is that people calculate using their 10 fingers when they do not have hard-to-reach tools such as paper and pencil. In ancient times, Greek mathematicians tried to calculate the width of the universe using the decimal number system, while Chinese mathematicians prepared their abacuses according to the decimal system.
