Step-by-Step Conversion

Step 1: Identify Each Hex Digit

The hex number BFAABFAABFE8 has 12 digit(s):

B = 11, F = 15, A = 10, A = 10, B = 11, F = 15, A = 10, A = 10, B = 11, F = 15, E = 14, 8 = 8

Step 2: Calculate Positional Values

Multiply each digit by its positional power of 16:

B (11) × 16¹¹ = 11 × 17,592,186,044,416 = 193,514,046,488,576
F (15) × 16¹⁰ = 15 × 1,099,511,627,776 = 16,492,674,416,640
A (10) × 16⁹ = 10 × 68,719,476,736 = 687,194,767,360
A (10) × 16⁸ = 10 × 4,294,967,296 = 42,949,672,960
B (11) × 16⁷ = 11 × 268,435,456 = 2,952,790,016
F (15) × 16⁶ = 15 × 16,777,216 = 251,658,240
A (10) × 16⁵ = 10 × 1,048,576 = 10,485,760
A (10) × 16⁴ = 10 × 65,536 = 655,360
B (11) × 16³ = 11 × 4,096 = 45,056
F (15) × 16² = 15 × 256 = 3,840
E (14) × 16¹ = 14 × 16 = 224
8 (8) × 16⁰ = 8 × 1 = 8

Step 3: Sum All Values

Add all the positional values together:

BFAABFAABFE8₁₆ = 210,740,080,984,040₁₀

What is Hexadecimal?

Hexadecimal (often called "HEX") is a base-16 numbering system that uses 16 unique symbols to represent values. It uses the standard digits 0-9 for values zero through nine, and the letters A through F (or a-f) for values ten through fifteen:

Why is Hexadecimal Important?

Compact binary representation: Each HEX digit maps to exactly 4 binary bits. This makes HEX perfect for representing binary data in a human-readable format.
Web colors: CSS color codes use hex notation like #FF5733 (orange-red), where each pair represents RGB values.
Memory addresses: Computer memory locations are typically displayed as hex values (e.g., 0x7FFF0000).
MAC addresses: Network hardware identifiers use hex pairs (00:1A:2B:3C:4D:5E).
Programming: Assembly language, debugging, and low-level programming frequently use hexadecimal notation.

How to Convert Hexadecimal to Decimal

To convert a hexadecimal number to decimal, multiply each digit by 16 raised to the power of its position (starting from 0 on the right), then sum all the results:

Hex 1A3 = (1 × 16²) + (A × 16¹) + (3 × 16⁰)
= (1 × 256) + (10 × 16) + (3 × 1)
= 256 + 160 + 3 = 419

How to Convert Hexadecimal to Binary

Converting HEX to binary is straightforward because each HEX digit corresponds to exactly 4 binary bits. Simply replace each HEX digit with its 4-bit binary equivalent:

Hex FA5 → F = 1111, A = 1010, 5 = 0101
Binary: 1111 1010 0101

Frequently Asked Questions

What is hexadecimal and how does it work?

Hexadecimal (HEX) is a base-16 number system using digits 0-9 and letters A-F. Each HEX digit represents a value from 0 to 15: A=10, B=11, C=12, D=13, E=14, F=15. One HEX digit equals exactly 4 binary bits, making it perfect for representing binary data compactly. For example, HEX FF equals binary 11111111 equals decimal 255.

How do I convert hexadecimal to decimal?

To convert HEX to decimal: multiply each HEX digit by 16 raised to its position power (starting from 0 on the right), then sum the results. For example, HEX 1A3 = (1 × 16²) + (10 × 16¹) + (3 × 16⁰) = 256 + 160 + 3 = 419 in decimal.

How do I convert hexadecimal to binary?

Converting HEX to binary is straightforward: replace each HEX digit with its 4-bit binary equivalent. For example, HEX F = 1111, HEX A = 1010, HEX 5 = 0101. So HEX FA5 becomes 1111 1010 0101 in binary. This 1-to-4 mapping makes HEX ideal for representing binary data.

What does the 0x prefix mean in hexadecimal?

The 0x prefix is a common convention in programming languages (C, Python, JavaScript, etc.) to indicate that a number is hexadecimal. For example, 0xFF means hexadecimal FF (decimal 255). Without the prefix, the number might be confused with decimal. This converter accepts both formats.

Where is hexadecimal commonly used?

Hexadecimal is used extensively in computing: HTML/CSS color codes (#FF5733), memory addresses (0x7FFF0000), MAC addresses (00:1A:2B:3C:4D:5E), Unicode characters (U+0041), binary file editing, assembly language, and debugging. Its compactness and direct binary mapping make it ideal for these applications.
