Many developers convert the decimal number to hexadecimal and then save that number to the database. And when they want to retrieve that number, they convert hexadecimal to decimal and then show it to the users. This translation is useful for embedded systems because decimal numbers are used in the embedded systems heavily. As a matter of fact, humans can easily read and recognize decimal numbers.

So, decimal numbers can be a threat to humans. That is why hexadecimal to decimal conversion is really important.

Hexadecimal is a base 16 numbering system which is made up of 16 digits: 0 — 9 and six more, which is A through F.

The table below shows how hexadecimal system works and its equivalent decimal number:. If decimal numbers have place values like ones, tens, hundreds, thousands and so on, hexadecimal numbers have place values as well. Decimals have powers of 10 while Hexadecimals have powers of
