2DF 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 number2DF:

216 = 00102

D16 = 11012

F16 = 11112

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: 001 011 011 111

With Zeros: 001 011 011 111

Convert each group of binary digits to its octal equivalent:

0012 = 18

0112 = 38

0112 = 38

1112 = 78
