Basic Knowledge
How to Convert from Binary to Hexadecimal
Since one hexadecimal digit corresponds exactly to four binary digits, you can convert by simply dividing the binary number into groups of four digits from the right and replacing each group.
- Conversion Example：The binary number 10100110, when divided into groups of four digits, becomes 1010 and 0110, which correspond to hexadecimal A and 6 respectively, resulting in A6.
- Range of Correspondence：Binary 0000 through 1111 correspond to hexadecimal 0 through F, and values equivalent to decimal 10 through 15 are represented by the letters A through F.
Where Is Hexadecimal Used?
Hexadecimal is widely used in color codes (such as #FF0000), memory addresses, and character code notation because it allows long binary numbers to be expressed more concisely and readably.
