Convert from Hexadecimal (Base 16) to Decimal (Base 10)
On this page you can perform the conversion of units of Hexadecimal (Base 16) to Decimal (Base 10)
Information on conversion units:
About Hexadecimal (Base 16):
The hexadecimal system reduces an eight-bit number to only two hexadecimal digits. This reduces the confusion that can arise when reading long strings of binary numbers and the amount of space required when writing binary numbers.
About Decimal (Base 10):
The Decimal Numbering System is a positional numbering system and is the system we all use without realizing why. The Decimal System uses 10 digits (from 0 to 9). By combining these digits, larger numbers can be expressed.

¿How to convert from Hexadecimal (Base 16) to Decimal (Base 10)?
Note: To convert a number in hexadecimal format (base 16) to any other base, we must first convert the hexadecimal value to decimal base (base 10), for this we must follow these steps:
- Identify each digit of the hexadecimal number.
- Calculate the position of each digit. Start from the rightmost digit, which will have a position of 0. Each digit to the left will have an incremental position of 1 (1, 2, 3, etc.).
- Calculate the decimal value of each digit by multiplying it by the base (16) raised to the digit's position. For example: digit * 16^position
- Sum the values obtained in the previous step to obtain the equivalent decimal number.
Applying these steps to the hexadecimal number 9F:
- 9 and F are the digits.
- From rightmost to leftmost, the positions are 0 and 1.
- 9 * 16^1 = 144; F (which equals 15 in decimal) * 16^0 = 15.
- 144 + 15 = 159 decimal.
So, 9F hexadecimal = 159 decimal.
