Hex to Decimal

Hexadecimal Base-16 String

A hex to decimal converter is a technical utility that translates numbers from the Base-16 (hexadecimal) system to the Base-10 (decimal) system. Hexadecimal is the language of computer memory, color codes, and networking (MAC addresses), while decimal is the standard system used in daily life. Our converter allows you to instantly translate complex alphanumeric strings into their numerical equivalents. Whether you are a programmer debugging a memory address, a web designer analyzing a hex color, or a student learning about number bases, this tool provides a fast and error-free bridge between the human and machine worlds.

How to Use Hex to Decimal Step by Step

Enter "Hexadecimal" — input the hex string (e.g., `1A`, `FF`, or `2A3B`).
Check "Case Sensitivity" — our tool handles both uppercase and lowercase inputs.
Click "Convert" — the tool will apply the positional multiplication logic.
Review the "Decimal Result" — see the value in standard Base-10 instantly.
Check the "Step-by-Step" — see how the power of 16 is applied to each digit.
Copy the Result — use the one-click button to save the decimal value.

Hex to Decimal Formula Explained

Σ (d_i × 16^i)

d_i

Digit Value

The value of the hex character (0-9 are literal, A-F are 10-15).

16^i

Position Weight

The power of 16 corresponding to the position of the digit (starting from 0 at the right).

Hexadecimal is a "Positional" system. To convert to decimal, we multiply each digit by 16 raised to the power of its position. For example, to convert `1A3`: `(1 × 16²) + (A × 16¹) + (3 × 16⁰)`. Substituting the value of `A` (10), we get: `(1 × 256) + (10 × 16) + (3 × 1) = 256 + 160 + 3 = 419`. Our converter automates this "Expansion" process, handling even massive hex strings with 100% mathematical precision.

Hex to Decimal — Worked Examples

Example 1 — Standard Hex Value

Converting the byte value "FF" into decimal.

Who Uses Hex to Decimal?

Software Developers

Translating hex-based memory addresses, error codes, and offsets into decimal for debugging and documentation.

Web Designers

Deconstructing Hex color codes (like #FFA500) into their RGB decimal components to understand color intensity.

Network Engineers

Analyzing MAC addresses and IPv6 segments to understand routing and hardware identification.

Students

Practicing number base conversions and verifying homework assignments for computer science classes.

Common Hex to Decimal Mistakes to Avoid

⚠️Invalid Characters

Using letters beyond "F" (like G or H). Hex only supports 0-9 and A-F.

⚠️Ignoring Position

Thinking "10" hex is the same as "10" decimal. "10" hex is actually 16.

⚠️Confusing Case

Thinking "A" and "a" are different. In hexadecimal, they both represent the value 10.
