Number Base Converter

Convert between decimal, binary, octal, hexadecimal and base-36 instantly.

Number Base Converter translates integers between decimal (base 10), binary (base 2), octal (base 8), hexadecimal (base 16), base 32, and base 36, displaying all representations simultaneously so you can see the same value in every numeral system at a glance. Computer science students use it to understand how the same number is represented differently in different systems. Developers use it to work with memory addresses, bit flags, color codes, and permissions (chmod values use octal). Embedded systems engineers use it to decode binary register values. Network engineers use it to understand IPv4 subnet masks in binary and decimal. The converter also accepts input in any base so you can start from hex, octal, or binary and see the decimal equivalent alongside all other forms.
