E55 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 numberE55:

E16 = 11102

516 = 01012

516 = 01012

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: 111 001 010 101

With Zeros: 111 001 010 101

Convert each group of binary digits to its octal equivalent:

1112 = 78

0012 = 18

0102 = 28

1012 = 58
