HEX to Decimal

In mathematics and computer science, hexadecimal (also base 16, or hex) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0–9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively a–f) to represent values ten to fifteen.

What is HEX ?

HEX is a number system with a base of 16. This number system is used in computers because it is easy to convert between binary (the number system with a base of 2 that computers use) and hexadecimal. In the HEX system, each digit can represent a value from 0 to 15. The first ten digits (0-9) represent the numbers 0-9 normally, while the last six digits (A-F) represent the values 10-15. To convert from HEX to decimal, simply multiply each digit by its place value and add up all the results. For example, the HEX number 3C7 would be equal to 3*16^2 + 12*16^1 + 7*16^0 = 951 in decimal.

What is Decimal ?

Decimal is the base 10 number system, which means that it uses 10 digits (0 – 9). It is our standard counting system, and is used worldwide. The decimal system is often called “denary” or “dec” for short.

When we count in decimal, each digit has a value 10 times that of the digit to its right. So the number 123 means 1×100 + 2×10 + 3×1.

The number 0 is special, because it denotes the absence of any quantity. So 123 means one hundred and twenty-three, but 1230 means one thousand two hundred and thirty.

The value of each digit also depends on its position in the number. In 123, the 3 has a value of 3 (1×1), but in 1230 it has a value of 300 (3×10²). This is why 1230 is ten times as big as 123 – each digit is moved one place to the left, and its value increases tenfold.
