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 number1F1:

116 = 00012

F16 = 11112

116 = 00012

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.
