Converting an octal number to hexadecimal without a calculator involves first converting the octal number to binary, then grouping the binary digits into groups of four, and finally converting each group to its hexadecimal equivalent. Here's a step-by-step guide for octal number4365:

Convert each octal digit to its 3-bit binary equivalent:

48 = 1002

38 = 0112

68 = 1102

58 = 1012

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