1D3 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 number1D3:

116 = 00012

D16 = 11012

316 = 00112

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: 000 111 010 011

With Zeros: 000 111 010 011

Convert each group of binary digits to its octal equivalent:

0002 = 08

1112 = 78

0102 = 28

0112 = 38
