## How To Convert 1f From Hexadecimal To Decimal

How to convert 1f from hexadecimal to decimal number? First we convert all hex digits into decimal values(table is found above). Then we solve the math equation below by multiplying all decimal digits with their corresponding powers of sixteen. After that we add up all left over numbers.

1*161 + f*160 =31

The answer is 1f16 converts to 3110

All digits and letters in a hexadecimal value contain the power of 16. This power of 16 is always growing bigger with each digit. The first digit from the right represents 160, the second is 161, the third is 162 and this continues(163,164,165...). In order to get the correct decimal value of it's hexadecimal counter part you need to calculate the sum of the powers of 16 for each hex digit.
