# Hex to Decimal Converter

**convert a hex value to a decimal**. Hex is a number system made up of 16 symbols (base 16). Decimal is made up of 10 symbols (base 10).

## Hex and decimal conversions

Decimals are numbers as we use them in our daily lives; whole numbers, like those used for counting items. Decimal is called **base 10**, because it uses 10 distinct numbers to count.

i.e. **0, 1, 2, 3, 4, 5, 6, 7, 8, 9.**

Hex numbers, or "hexadecimal", to use its full name, is **base 16**. It uses 16 distinct characters to count.

i.e. **0, 1, 2, 3, 4, 5, 6, 7, 8, 9,** plus the letters **A, B, C, D, E, F.**

Putting these numbers side by side, we can get an idea of how to convert the most basic of decimal numbers to hex:

### Hex to decimal reference list

0 1 2 3 4 5 6 7 8 9 A B C D E F0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Seeing decimal and hex numbers together like this, we can easily see that **10** in decimal is the same as **A** in hex, and **15** in decimal is **F** in hex.

## How to convert from hex to decimal

- Take a hex number and, starting from the right of it, take each character one at a time.
- Look up the corresponding decimal in the hex-decimal comparison list above (e.g. A = 10, F = 15).
- Multiply that corresponding decimal by an increasing multiple (power) of 16 (e.g. 16
^{0}, 16^{1}, 16^{2}etc). - Add up the results.

### Example of hex to decimal conversion

Let's take the hex number **A3C2**. It is made up of A, 3, C, 2. So we start on the right, with **2**, and work backwards.

- 2 x (16
^{0}) = 2 x 1 =**2** - C x (16
^{1}) =**12**x 16 =**192** - 3 x (16
^{2}) = 3 x (16 x 16) = 3 x 256 =**768** - A x (16
^{3}) =**10**x (16 x 16 x 16) = 10 x 4096 =**40960**

Add the results together:

- 2 + 192 + 768 + 40960 =
**41922**

**So the decimal equivalent of A3C2 is 41922.**

## Hex converted to HTML

**Hex numbers** have been used in groups of six digits to represent colours on the World Wide Web. This is because a six-digit hex number represents the three colours red, blue and green (RGB), as three groups of two digits.

Taking as an example the colour purple, it's represented as **FF00FF**.

If we split this down, we can see the three groups:

FF 00 FF | Red | Green | Blue |

FF00FF represents purple because **FF** is the highest two-digit hex number possible, while **00** is the lowest. Red and blue mixed together form the colour purple.

**Note:** If a valid six-digit (or three-digit) hex number is entered in our **hex to decimal converter**, the corresponding set of decimal
RGB values will also be given, in addition to the overall decimal result.
