### How to convert from octal 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
Octal numbers are read the same way, but each digit counts 8n instead of 10n.
Multiply each digit of the hex number with its corresponding 8n.

#### Example #2

37 in base 8 is equal to each digit multiplied with its corresponding 8n:
378 = 3×81+7×80 = 24+7 = 31

#### Example #3

70148 = 7×83+0×82+1×81+4×80= 3584+0+8+4 = 3596
