Hex to Decimal Table

Every hex value 0-255 paired with its decimal equivalent — a focused two-column table for quick hex-to-decimal lookups.

How to Read This Table

Each row pairs one hex value (0x00-0xFF) with its decimal equivalent (0-255). Scan down the hex column for the value you have, or the decimal column for the value you're converting to.

Where This Table Actually Comes Up

Quickly Checking a Byte Value's Decimal Equivalent

Scanning several hex values from a hex dump against their decimal equivalents at once, faster than converting one at a time.

0x7F -> 127, 0x80 -> 128

Memorizing Common Byte Boundaries

Building familiarity with frequently referenced values like 127, 128, and 255 and their hex equivalents through repeated exposure to the full range.

0x7F = 127 (signed max), 0xFF = 255 (unsigned max)

Cross-Checking a Calculator's Output

Verifying a hex-to-decimal converter's result against a known reference table value, useful when testing or learning.

Limitations

Covers single-byte values (0-255) only — use the Hex to Decimal Converter directly for larger values.

Frequently Asked Questions

Why just hex and decimal, not binary too?

Keeping the table to two columns makes it faster to scan when decimal is specifically what you're after — see the Hexadecimal Table if you want hex, decimal, and binary together.

How do I convert a hex value to decimal without the table?

Multiply each hex digit by 16 raised to its position (counting from 0 on the right), then add the results — see Hex to Decimal for a calculator and worked example.

Why does this table stop at 255?

255 (0xFF) is the largest value a single byte can hold — this covers the full range of one byte, the most commonly referenced range for this kind of lookup.

Is there a faster way to find one specific value?

Use your browser's find-in-page (Ctrl+F / Cmd+F) and search for the hex or decimal value you're looking for.
