This free online binary to hexadecimal calculator will convert binary numbers into hexadecimal numbers and display a conversion chart to show how it calculated the answer.
If you're not sure what a binary number is, or you would like to convert a binary number to a decimal number instead, please visit the binary to decimal conversion calculator for a more detailed explanation.
Or, if you are not familiar with what a hexadecimal number is, please visit the decimal to hexadecimal conversion calculator page for a description.
If you would like to perform the conversion manually instead of using the binary to hex converter, here are the 5 steps for manually converting a binary (base 2) number into a hexadecimal (base 16) number:
Step #1: Working from right to left, split the binary number into groups of 4 digits. If the leftmost grouping has less than 4 digits, make up the difference with zeros. To illustrate this step, as well as the steps that follow, we will use the binary number 11001101101.
A  Binary groups of 4:  0  1  1  0  0  1  1  0  1  1  0  1 
Step #2: Populate the next row with "8 4 2 1" under each grouping. The 8421 represents the binary place values for each of the four positions, the combination of which total up to 15 (the highest digit that can be used in a base 16 number, similar to the "9" in the decimal system).
A  Binary groups of 4:  0  1  1  0  0  1  1  0  1  1  0  1  
B  Binary place value :  8  4  2  1  8  4  2  1  8  4  2  1 
Step #3: Multiply the each digit in Row A by the corresponding place value in Row B and place the result in Row C.
A  Binary groups of 4:  0  1  1  0  0  1  1  0  1  1  0  1  
B  Binary place value :  8  4  2  1  8  4  2  1  8  4  2  1  
C  Product of A * B:  0  4  2  0  0  4  2  0  8  4  0  1 
Step #4: Add the products in Row C for each group of 4 and place the total in Row D.
A  Binary groups of 4:  0  1  1  0  0  1  1  0  1  1  0  1  
B  Binary place value :  8  4  2  1  8  4  2  1  8  4  2  1  
C  Product of A * B:  0  4  2  0  0  4  2  0  8  4  0  1  
D  Sum of 4 C's:  6  6  13 
Step #5: Change any values in Row D that are greater than 9 into the hexadecimal letter they are represented by.
A  Binary groups of 4:  0  1  1  0  0  1  1  0  1  1  0  1  
B  Binary place value :  8  4  2  1  8  4  2  1  8  4  2  1  
C  Product of A * B:  0  4  2  0  0  4  2  0  8  4  0  1  
D  Sum of 4 C's:  6  6  13  
E  Hexadecimal digit :  6  6  D 
So you see, the binary number 11001101101 converts to the hexadecimal number 66D, which can be written as 66D_{16}, 66Dh, or 0x66D.
With that, let's use the Binary to Hex Converter to convert base 2 to base 16.
