Calculator of the hex number system

This online service translates the number from the hexadecimal notation system to any other. The number can be any non-negative. The base of the notation system for the translation from 2 to 36 inclusive.

In the form of a calculator, enter a number in the hexadecimal system, then specify the notation system to which you want to translate the number and click "Calculate".


A notation system, or numbering, is a set of rules and signs that can be used to map (encode) any non-negative number. There are certain requirements on the number systems, among which the most important are the requirements for unambiguous coding of nonnegative numbers 0, 1,... from some finite set of the range P in a finite number of steps and the ability to perform numerically arithmetic and logical operations. In addition, the number system solves the numbering problem, that is, an effective transition from digits to numbers, which in this case must have a minimum number of digits. From the successful or unsuccessful choice of the number system depends the effectiveness of solving these problems and its use in practice.

Hexadecimal notation is a positional number system with base 16. That is, each number in it is written using 16 symbols. Arabic numerals from 0 to 9 correspond to values from zero to nine, and 6 letters of the Latin alphabet A, B, C, D, E, F correspond to values from ten to fifteen. Hexadecimal number system is widely used by computer developers and programmers.

This system is also often called Hex.

Each hexadecimal digit is represented by four binary digits (bits), and the main use of a hexadecimal record is a convenient binary code entry. One hexadecimal digit is a nibble, which is half octet or byte (8 bits). For example, the byte value ranges from 0 to 255 (in decimal numbers), but can be more conveniently represented as two hexadecimal digits in the range from 00 to FF. A hexadecimal system is also widely used to represent the memory address of a computer.
