The below step-by-step solution using the most easiest method shows how to convert (1220)8 into decimal equivalent. To find the decimal equivalent of (1220)8, 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 1220. The sum of all individual products is the decimal equivalent of octal 1220.
Solved Example:
Convert (1220)8 into decimal equivalent.
step 1 Observe the input parameters, values and what to be found.

Input values:
Octal Number = 1220₈

What to be found:
What is the decimal equivalent of (1220)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 1220. Therefore, arrange the given decimal number 1220 in the expression form as like the below:
= (1 x 8³) + (2 x 8²) + (2 x 8¹) + (0 x 8⁰)

step 3 Resolve the powers of 8 in the above equation:
= (1 x 512) + (2 x 64) + (2 x 8) + (0 x 1)

step 3 Simplify the above equation further:
= 512 + 128 + 16 + 0
= 656
(1220)₂ = (656)₁₀

Therefore,
656 is the decimal equivalent of octal number (1220)8
