Conversion from decimal to octal

Decimal numbers are standard systems that are easily understood by humans. However, digital circuits operate on binary numbers, and some operations are necessary in decimal, octal. It can be implemented by a continuous division method. The following example will show you how to convert its equivalent octal number to decimal

Example: Convert decimal number 143 to equivalent octal

Step 1: The quotient and remainder of the decimal number 8 will be 17 and 7, respectively.

Step 2: Then divide 8 by the quotient of 17 and the remainder 2 and 1 respectively

Step 3: Divide by 2 cannot be divided by 8

Step 4: To make the final number, write the last quotient first, and write the remainder from the bottom to the top

The equivalent octal number is (217)

Octal to decimal conversion

For example: 143 octal number converted to decimal

= 1 x 8² + 4 x 8¹ + 3 x 8⁰

= 1 x 64 + 4 x 8 + 3 x 1

= 64 + 32 + 3

= 99
