How to Convert from Decimal to Hexadecimal

To convert a number from decimal to hexadecimal, we divide the number by 16 and record the remainder. We repeat this process until the division results in zero. Then, we read the remainders in reverse order.

Example 1: Converting 255 to Hexadecimal

1. 255 / 16 = 15 remainder 15 → record F
2. 15 / 16 = 0 remainder 15 → record F

Thus, the result is: 255₁₀ = FF₁₆.

Example 2: Converting 26 to Hexadecimal

1. 26 / 16 = 1 remainder 10 → record A
2. 1 / 16 = 0 remainder 1 → record 1

Thus, the result is: 26₁₀ = 1A₁₆.
