Convert numbers between binary, octal, decimal, and hexadecimal instantly.
Convert numbers instantly between binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16). Type in any field to update all others.
A: Type or paste your binary number (e.g. 1010) into the Binary field. The decimal equivalent updates instantly in the Decimal field.
A: Hex is widely used in programming for memory addresses, colour codes (e.g. #FF5733), byte representations, and debugging binary data.
A: Yes. The converter uses JavaScript BigInt, so it handles arbitrarily large integers without floating-point precision issues.
A: Grouping binary digits into nibbles (4-bit groups) makes the value easier to read and aligns naturally with hexadecimal where one hex digit equals exactly four binary digits.
