Solved Example:
Convert (1231)8 into decimal equivalent.
step 1 Observe the input parameters, values and what to be found.
Input values:
Octal Number = 12318
What to be found:
What is the decimal equivalent of (1231)8?
step 2 Multiply 80 with the right most digit, 81 with the left subsequent digit and so on until the left most digit of the given octal number 1231. Therefore, arrange the given decimal number 1231 in the expression form as like the below:
= (1 x 83) + (2 x 82) + (3 x 81) + (1 x 80)
step 3 Resolve the powers of 8 in the above equation:
= (1 x 512) + (2 x 64) + (3 x 8) + (1 x 1)
step 3 Simplify the above equation further:
= 512 + 128 + 24 + 1
= 665
(1231)2 = (665)10
