## How to Convert Hexadecimal to Decimal ### Method Hexadecimal (base-16) uses digits 0-9 and letters A-F (where A=10, B=11, C=12, D=13, E=14, F=15). Enter the numeric value of each hex digit (0-15). **Decimal = d3×4096 + d2×256 + d1×16 + d0×1** For example, hex FF (enter 15, 15): 15×16 + 15×1 = 240 + 15 = 255.

Häufig Gestellte Fragen
What is hexadecimal?
Hexadecimal (base-16) uses 16 symbols: 0-9 and A-F. It is widely used in computing to represent binary data compactly, since each hex digit corresponds to exactly 4 binary bits.
Why is hex used in computing?
Hexadecimal provides a compact way to represent binary. One hex digit equals 4 bits, so a byte (8 bits) is exactly 2 hex digits. This makes it easier to read and write binary values.
What do A-F represent in hex?
A=10, B=11, C=12, D=13, E=14, F=15. Enter these numeric values in the input fields.
