# How to use

Our **Binary to Hexadecimal** calculator will convert your binary value (tipically used by computers) of the number you enter to an hexadecimal value. Your results will appear in the blank field at the bottom.

# Manually conversion

First, look with attention the following table:

Write out the hexadecimal in its expanded form. For example, 1A2B3C16 becomes:

(1 x 16^{5}) + (10 x 16^{4}) + (2 x 16^{3}) + (11 x 16^{2}) + (3 x 16^{1}) + (12 x 16^{0})

# Binary System

**Binary **is the simplest kind of number system that uses only two digits of 0 and 1 (**base 2**). By using these digits computational problems can be solved by machines because in digital electronics a transistor is used in **two states**. Those two states can be represented by 0 and 1. That is why this number system is the most preferred in modern** computer engineer**, **networking **and communication specialists, and other professionals.

# Hex System

Hex, or **hexadecimal**, is a number system of **base 16**. This number system is especially interesting because in our casually used decimal system we have only 10 digits to represent numbers. As hex system has 16 digits, the extra needed 6 digits are represented by the first 6 letters of English alphabet. Hence, hex digits are 0,1,2,3,4,5,6,7,8 and 9 A, B, C, D, E, F.

This number system is the most commonly used in mathematics and information technologies. I.e. in html programming colors can be represented by a 6-digit hexadecimal number: **FFFFFF **represents **white**, **000000 **represents **black**, and so on.
