Everything you need to know about octal to hex conversion
Octal to hex conversion transforms octal numbers (base-8, using digits 0-7) into hexadecimal numbers (base-16, using digits 0-9 and A-F). This conversion is useful in programming and digital systems.
First convert octal to decimal by multiplying each digit by its power of 8, then convert decimal to hex by repeatedly dividing by 16. For example: octal 57 = (5×8¹ + 7×8⁰) = 47 decimal = 2F hex.
Both octal and hex are compact representations of binary data. Converting between them is useful when working with different systems that prefer different number bases, such as Unix permissions (octal) and memory addresses (hex).
Our converter handles standard integer ranges efficiently. The conversion follows mathematical principles and remains accurate for all valid octal inputs within typical programming ranges.
Octal represents groups of 3 binary digits (bits) while hexadecimal represents groups of 4 binary digits. Both provide compact ways to represent binary data, making them useful in different computing contexts.
