Remember that "A" in hex is equivalent to 10 in decimal. The second "A" from the right represents 16 1, and the 2 represents 16 2. Starting from the right, the first "A" represents the "ones" place, or 16 0. This means that for the value 2AA, each place value represents a power of 16. As previously mentioned, hex functions using the base of 16. The ability to perform the conversion of either should make the other relatively simple. Note that converting between decimal and hex is quite similar to converting between decimal and binary. A more in-depth discussion is available on the binary calculator page. This helps computers to compress large binary values in a manner that can be easily converted between the two systems.īelow are some typical conversions between hex, binary, and decimal values:Ĭonverting between decimal and hex involves understanding the place values of the different number systems. For example, the binary value of 1010101010 can be represented as 2AA in hex.
Every hex digit represents 4 binary digits, called nibbles, which makes representing large binary numbers simpler. Hex uses 16 digits including 0-9, just as the decimal system does, but also uses the letters A, B, C, D, E, and F (equivalent to a, b, c, d, e, f) to represent the numbers 10-15. Instead of using a base of 10 or 2 respectively, it uses a base of 16. The hexadecimal number system (hex) functions virtually identically to the decimal and binary systems. So the bold digits are 1 and the others are 0.Related Binary Calculator | IP Subnet Calculator (Notice the bold digits sum up to the hex value above. Let's apply these steps to the hex number (4FA) 16
Step 5: Read the 1’s and 0’s from left to right to get the binary equivalent of the given hex number.Write down 0 below those that are not used. Step 4: Write down 1 below those 8, 4, 2 and 1’s that are used.If your hex number is 2, only 2 is used 8, 4 and 1 are not. For example, if one of your hex values is 10, this means 8 and 2 sum up to 10 (4 and 1 are not used). Step 3: Determine which powers of two (8, 4, 2 or 1) sum up to your hex digits.Write these numbers (8, 4, 2 and 1) below the hex values. The rightmost digit equals to 2 0 (1), the next one equals to 2 1 (2), the next one equals to 2 2 (4) and the leftmost one equals to 2 3 (8). Step 2: Each hex digit represents four binary digits and therefore is equal to a power of 2.If there are any, change the hex values represented by letters to their decimal equivalents. You just need to remember that each hex value will produce four binary digits.

How to Convert Hex to BinaryĬonverting from hex to binary is straightforward since hexadecimal numbers are simplified versions of binary strings. In the binary system, each binary digit refers to 1 bit. Reading a binary number is easier than it looks: This is a positional system therefore, every digit in a binary number is raised to the powers of 2, starting from the rightmost with 2 0. Even the digital text that you are reading right now consists of binary numbers.

It is also the basis for binary code that is used to compose data in computer-based machines. This is the most efficient system to detect an electric signal’s off (0) and on (1) state.
While it has been applied in ancient Egypt, China and India for different purposes, the binary system has become the language of electronics and computers in the modern world. As a base-2 numeral system, it consists of only two numbers: 0 and 1. The binary numeral system uses the number 2 as its base (radix).
