Out of curiosity, how exactly does binary code get converted into letters? I know there are sites that automatically convert binary to words for you but I wanna understand the specific, intermediary steps that binary code goes through before being converted into letters.

How to Convert Binary to Text - EASIEST TUTORIAL, In this tutorial, I am going to show you how to convert binary into text that you can read! It Duration: 6:49 Posted: Aug 21, 2018 If you want to convert any binary-encoded text to ASCII, you can use the Binary to Text Translator at What does 01101001 mean? 01101001 is the binary encoding of the ASCII code 105, which represents the character i , as you can verify with the binary translator .

Here's a way to convert binary numbers to ASCII characters that is often simple enough to do in your head.

1 - Convert every 4 binary digits into one hex digit.

Here's a binary to hex conversion chart:

0001 = 1 
0010 = 2 
0011 = 3 
0100 = 4 
0101 = 5
0110 = 6
0111 = 7
1000 = 8

1001 = 9
1010 = a (the hex number a, not the letter a)
1011 = b
1100 = c
1101 = d
1110 = e
1111 = f

(The hexadecimal numbers a through f are the decimal numbers 10 through 15. That's what hexadecimal, or "base 16" is - instead of each digit being capable of representing 10 different numbers [0 - 9], like decimal or "base 10" does, each digit is instead capable of representing 16 different numbers [0 - f].)

Once you know that chart, converting any string of binary digits into a string of hex digits is simple.

For example,

01000100 = 0100 0100 = 44 hex
1010001001110011 = 1010 0010 0111 0011 = a273 hex

Simple enough, right? It is a simple matter to convert a binary number of any length into its hexadecimal equivalent.

(This works because hexadecimal is base 16 and binary is base 2 and 16 is the 4th power of 2, so it takes 4 binary digits to make 1 hex digit. 10, on the other hand, is not a power of 2, so we can't convert binary to decimal nearly as easily.)

2 - Split the string of hex digits into pairs.

When converting a number into ASCII, every 2 hex digits is a character. So break the hex string into sets of 2 digits.

You would split a hex number like 7340298b392 this into 6 pairs, like this:

7340298b392 = 07 34 02 98 b3 92

(Notice I prepended a 0, since I had an odd number of hex digits.)

That's 6 pairs of hex digits, so its going to be 6 letters. (Except I know right away that 98, b3 and 92 aren't letters. I'll explain why in a minute.)

3 - Convert each pair of hex digits into a decimal number.

Do this by multiplying the (decimal equivalent of the) left digit by 16, and adding the 2nd.

For example, b3 hex = 11*16 + 3, which is 110 + 66 + 3, which is 179. (b hex is 11 decimal.)

4 - Convert the decimal numbers into ASCII characters.

Now, to get the ASCII letters for the decimal numbers, simply keep in mind that in ASCII, 65 is an uppercase 'A', and 97 is a lowercase 'a'.

So what letter is 68?

68 is the 4th letter of the alphabet in uppercase, right? 65 = A, 66 = B, 67 = C, 68 = D.

So 68 is 'D'.

You take the decimal number, subtract 64 for uppercase letters if the number is less than 97, or 96 for lowercase letters if the number is 97 or larger, and that's the number of the letter of the alphabet associated with that set of 2 hex digits.

Alternatively, if you're not afraid of a little bit of easy hex arithmetic, you can skip step 3, and just go straight from hex to ASCII, by remembering, for example, that

hex 41 = 'A' 
hex 61 = 'a'

So subtract 40 hex for uppercase letters or 60 hex for lowercase letters, and convert what's left to decimal to get the alphabet letter number.

For example

01101100 = 6c, 6c - 60 = c = 12 decimal = 'l'
01010010 = 52, 52 - 40 = 12 hex = 18 decimal = 'R'

(When doing this, it's helpful to remember that 'm' (or 'M') is the 13 letter of the alphabet. So you can count up or down from 13 to find a letter that's nearer to the middle than to either end.)

I saw this on a shirt once, and was able to read it in my head:


I did it like this:

01000100 = 0100 0100 = 44 hex, - 40 hex = ucase letter 4 = D
01000001 = 0100 0001 = 41 hex, - 40 hex = ucase letter 1 = A
01000100 = 0100 0100 = 44 hex, - 40 hex = ucase letter 4 = D

The shirt said "DAD", which I thought was kinda cool, since it was being purchased by a pregnant woman. Her husband must be a geek like me.

How did I know right away that 92, b3, and 98 were not letters?

Because the ASCII code for a lowercase 'z' is 96 + 26 = 122, which in hex is 7a. 7a is the largest hex number for a letter. Anything larger than 7a is not a letter.

So that's how you can do it as a human.

How do computer programs do it?

For each set of 8 binary digits, convert it to a number, and look it up in an ASCII table.

(That's one pretty obvious and straight forward way. A typical programmer could probably think of 10 or 15 other ways in the space of a few minutes. The details depend on the computer language environment.)

Binary code, In a fixed-width binary code, each letter, digit, or other character is represented by a bit string of the same length; that bit string, interpreted as a binary number, is  How to use the binary translator? Just write (or paste) the binary code into the translator, and then click the Translate button to get the conversion to ASCII (English text). Enter the Binary code here: Instant conversion No spaces. You can also convert any text to binary with our text to binary code translator.

Do you mean the conversion 011001100110111101101111foo, for example? You just take the binary stream, split it into separate bytes (01100110, 01101111, 01101111) and look up the ASCII character that corresponds to given number. For example, 01100110 is 102 in decimal and the ASCII character with code 102 is f:

$ perl -E 'say 0b01100110'
$ perl -E 'say chr(102)'

(See what the chr function does.) You can generalize this algorithm and have a different number of bits per character and different encodings, the point remains the same.

Binary Translator ▷ Convert Binary to Text, We'll add those together to get the decimal output, which is 67. So how does that correspond to a letter, especially since there's only 26 in the English alphabet? Use the above ASCII and Binary Codes of Alphabets Chart for reference and find the equivalent values between characters, ASCII code and binary codes. For example, the ASCII value for alphabet 'A' is 65 and binary code is 1000001, similarly ASCII value for alphabet 'a' is 97 and binary code is 1100001.

To read binary ASCII characters with great speed using only your head:

Letters start with leading bits 01. Bit 3 is on (1) for lower case, off (0) for capitals. Scan the following bits 4–8 for the first that is on, and select the starting letter from the same index in this string: "PHDBA" (think P.H.D., Bachelors in Arts). E.g. 1xxxx = P, 01xxx = H, etc. Then convert the remaining bits to an integer value (e.g. 010 = 2), and count that many letters up from your starting letter. E.g. 01001010 => H+2 = J.

Binary code, Binary code (or the binary system) is omnipresent in computer Starting at the beginning we get position 1 plus the first digit of the It was the task of pioneers in computing to translate numbers and letters into a system To perform a calculation, decimal numbers are converted into the binary system. We total the decimal values of each binary digit to get the decimal equivalent. So 1101001 (binary) is 105 (decimal). Converting Decimal to Binary We can convert a decimal to binary using the same procedure we used to convert decimal to octal or hex. The difference this time is that we divide by 2 each time since we are working in base 2. it just looks here... (not HERE but it has a table).

There are 8 bits in a byte. One byte can be one symbol. One bit is either on or off.
