Frequently Asked Questions
How do you convert decimal to hex?▾
Divide by 16 repeatedly. Record the remainder (0–15, represented as 0–F). Read remainders from bottom to top. E.g. 255 ÷ 16 = 15 r15 (F), 15 ÷ 16 = 0 r15 (F) → 0xFF.
What do the hex letters A–F mean?▾
A=10, B=11, C=12, D=13, E=14, F=15. These represent single digits in base-16 where values exceed 9.
Why is hex used in computing?▾
Each hex digit represents exactly 4 binary bits, making hex a compact and readable way to write binary data. 8-bit bytes map neatly to 2 hex digits (00–FF).
