Understanding how to convert decimal to binary and decimal to hexadecimal is
fundamental in computer science.
Decimal to Binary Conversion
To convert a decimal number to binary, you repeatedly divide the decimal number by 2 and record the remainder. You then read the remainders from bottom to top to get the binary equivalent.Example: Convert 13 (base 10) to Binary:
13 ÷ 2 = 6 remainder 1
6 ÷ 2 = 3 remainder 0
3 ÷ 2 = 1 remainder 1
1 ÷ 2 = 0 remainder 1
Reading remainders from bottom up: 1101 (base 2).
Decimal to Hexadecimal Conversion
To convert a decimal number to hexadecimal, you repeatedly divide the decimal number by 16 and record the remainder. If the remainder is 10-15, you use the corresponding hexadecimal digit (A-F). Read the remainders from bottom to top.Example: Convert 255 (base 10) to Hexadecimal:
255 ÷ 16 = 15 remainder 15 (which is 'F' in hex)
15 ÷ 16 = 0 remainder 15 (which is 'F' in hex)
Reading remainders from bottom up: FF (base 16).

Why Convert Decimal to Binary and Hexadecimal?
Number base conversions are crucial in various fields:- Computer Science & Programming: Computers fundamentally operate using binary (0s and 1s). Programmers often need to work with binary directly for low-level operations, or with hexadecimal as a more human-readable shorthand for large binary numbers (e.g., memory addresses, color codes, MAC addresses).
- Digital Electronics: Understanding how decimal values translate into binary is essential for designing and analyzing digital circuits.
- Data Representation: Different data types (integers, floating-point numbers, characters) are stored in memory using binary. Hexadecimal is frequently used to represent byte values compactly.
- Network Engineering: IP addresses, MAC addresses, and network packets often involve hexadecimal or binary representations.
