Five Easy Steps to Converting Binary to Hexadecimal

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 left-most 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.

Step #1: Create Groups of 4 Digits

ABinary groups of 4:0110 0110 1101 

Note that 1 zero was added to the front of the left-most grouping to make it a group of 4 digits.

Step #2: Populate the next row with "8 4 2 1" under each grouping. The 8-4-2-1 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).

Step #2: Place "8 4 2 1" Under Each Set of 4

BBinary place value :8421 8421 8421 

Step #3: Multiply each digit in Row A by the corresponding place value in Row B and place the result in Row C.

Step #3: Multiply Digits in Row A by Row B

BBinary place value:8421 8421 8421 
CProduct of A * B:0420 0420 8401 

Step #4: Add the products in Row C for each group of 4 and place the total in Row D.

Step #4: Add Products in Row C for Each Group

ABinary groups of 4:0110 0110 1101 
BBinary place value:8421 8421 8421 
CProduct of A * B:0420 0420 8401 
DSum 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.

Step #5: Convert Values Greater Than 9 to Hex Letters

ABinary groups of 4:0110 0110 1101 
BBinary place value :8421 8421 8421 
CProduct of A * B:0420 0420 8401 
DSum of 4 C's:6 6 13 
EHexadecimal digit :6 6 D 

In hexadecimal notation, A=10, B=11, C=12, D=13, E=14, and F=15. Note that the above is how the binary to hex converter shows its work for each conversion.

So you see, the binary number 11001101101 converts to the hexadecimal number 66D, which can be written as 66D16, 66Dh, or 0x66D.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
