CB Hex in Octal

Converting a hexadecimal number to octal without a calculator involves first converting the hexadecimal number to binary, then grouping the binary digits into groups of three, and finally converting each group to its octal equivalent. Here's a step-by-step guide for hexadecimal numberCB:

C16 = 11002

B16 = 10112

Group the binary digits into groups of three, starting from the right. If the last group has fewer than three digits, pad it with zeros on the left.

Binary: 11 001 011

With Zeros: 011 001 011

Convert each group of binary digits to its octal equivalent:

0112 = 38

0012 = 18

0112 = 38
