What Is the Decimal Number System?
The decimal number system is a base-10 system that uses digits from 0 to 9. It is the most common number system used in everyday calculations.
Example:
25 (decimal)
= (2 × 10¹) + (5 × 10⁰)
What Is the Hexadecimal Number System?
The hexadecimal number system is a base-16 system. It uses:
- Digits: 0–9
- Letters: A–F
Where:
- A = 10
- B = 11
- C = 12
- D = 13
- E = 14
- F = 15
Hexadecimal is preferred in computing because it represents large binary numbers in a short and readable format.
Formula to Convert Decimal to Hexadecimal
Decimal to hexadecimal conversion is done using the repeated division by 16 method:
- Divide the decimal number by 16
- Write down the remainder
- Divide the quotient again by 16
- Repeat until the quotient becomes 0
- Read the remainders from bottom to top
