How to convert from hex to decimal

A regular decimal number is the sum of the digits multiplied with 10n.

Example #1

137 in base 10 is equal to each digit multiplied with its corresponding 10n:

13710 = 1×102+3×101+7×100 = 100+30+7

Hex numbers are read the same way, but each digit counts 16n instead of 10n.

Multiply each digit of the hex number with its corresponding 16n.

Example #2

3B in base 16 is equal to each digit multiplied with its corresponding 16n:

3B16 = 3×161+11×160 = 48+11 = 59

Example #3

E7A9 in base 16 is equal to each digit multiplied with its corresponding 16n:

E7A916 = 14×163+7×162+10×161+9×160 = 57344+1792+160+9 = 59305
