Here we have explained the simple way to convert hexadecimal (hex) numbers to decimal, and also given an example which will make it easier for you to understand, you will use the steps given below.

Here we have given the formula to convert hexadecimal (hex) numbers to decimals below

Write down the hexadecimal number you want to convert. For example, let's use the hex number 1A3.

Here we will assign a decimal value to each hex digit. Its value is as given below.

1. • 0: 0
   • 1: 1
   • 2: 2
   • 3: 3
   • 4: 4
   • 5: 5
   • 6: 6
   • 7: 7
   • 8: 8
   • 9: 9
   • A: 10
   • B: 11
   • C: 12
   • D: 13
   • E: 14
   • F: 15
   • aa 170 bb 187 cc 204 dd 221 ee 238 ff 255 10 16 100 256 1000 4096 10000 65536
   • For example, in the hex number 1A3, '1' is 1 in decimal, 'A' is 10, and '3' is 3.
   • Multiply each digit by 16 raised to the power of its position (from right to left, starting with 0 as the rightmost position) and sum the results.
   • Calculation For example
   • 1. • $1\times 16^2$ for '1' in the hundreds place
        • $10\times 16^1$ for 'A' in the tens place
        • $3\times 16^0$ for '3' in the ones place

        $1\times 256+10\times 16+3\times 1=256+160+3=419$

        So, the decimal equivalent of the hex number 1A3 is decimal 419.
