Use the hex to decimal converter tool to instantly convert *hex to decimal* values and decimal to hex values.

Before you convert a decimal to ahexadecimal and a hexadecimal to a decimal you must know what decimal bits and hex bits are.

What Is a Decimal?

First, a decimal or hex bit represents a single number, digit, or letter. A decimal is also called base 10 and denary because it consists of ten numbers. These are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Decimals are the numbers we use in everyday counting. We mostly use the decimal number system because we have ten fingers. The number 10 is made by using a combination of two of these decimal numbers: 1 and 0, while a number like 209 is a combination of three decimal numbers: 2, 0, and 9.

There is no limit as to how many times the numbers can be reused. that’s why it is often said that numbers are never ending.

A hexadecimal, which is also called base 16 or « hex » for short, is a representation of four binary bits and consists of sixteen numbers and letters. The numbers in a hex are the same as decimal numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. The big difference between a hex and a decimal is that a hex also contains letters. These letters are: A, B, C, D, E, F.

A hex number can be represented using a subscript of 16 (i.e. 235_{16}). These letters come after the decimals in ascending order. Therefore, the hexadecimal series looks like this: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. A hex can be considered a shorter version of a decimal. For example a large number in decimal form has a much smaller hex equivalent (using less hex bits to represent the decimal number). I will demonstrate this later.
