Frequently Asked Questions

What characters are used in hexadecimal?

Hexadecimal uses 16 characters: digits 0-9 represent values 0-9, and letters A-F represent values 10-15. This allows larger numbers to be represented with fewer digits than decimal.

How do I convert decimal to HEX manually?

Divide the decimal number by 16 repeatedly, noting the remainders. The remainders read from bottom to top form the hexadecimal number. Remainders 10-15 become A-F.

Why is hexadecimal used in computing?

Hexadecimal is convenient in computing because each HEX digit represents exactly 4 binary bits (nibble). This makes it easy to read and write binary data compactly while maintaining a direct relationship with binary.
