1024 - Binary, Octal, Decimal & Hex Conversion

1024 in binary is 10000000000 (0100 0000 0000 with nibble spacing). Each hex digit maps to four bits, which is why 0x400 and grouped binary align visually. Copy the spaced form when documenting registers, teaching nibble alignment, or pasting constants into code review comments.

Decimal 1024 equals 0x400 in hexadecimal and 0o2000 in octal. Hex is compact for byte-aligned constants in C, Rust, and JavaScript (0x prefix). Paste either prefixed form into source after confirming the decimal column matches your intended magnitude exactly first.

1024 equals 2 to the power of 10. In computing that is 1 kibibyte (KiB); people often still call it a kilobyte, though SI kilobyte (KB) means 1000 bytes. RAM sizes, file buffers, and disk blocks are often multiples of 1024. This page shows 1024 as binary, hex, and octal so you can copy the form that matches your code or docs.

Convert to decimal first using positional notation, then divide repeatedly by the target base and record remainders. For hex↔binary, expand each hex nibble to four bits instead of converting through decimal. This page shows all four bases at once so you can spot-check homework, code review, or lecture examples quickly.

Programmer mode is excellent for chained bitwise operations and live bit toggling. This browser tool is faster when you need all four representations copied into documentation, pull requests, or lecture notes without switching apps or remembering mode shortcuts on every machine.

The main converter accepts any valid value in binary, octal, decimal, or hex with optional 0b, 0o, or 0x prefixes. Visit /dev-tools/binary-hex-decimal-converter/ for the interactive tool with digit validation, nibble-grouped binary output, and one-click copy buttons for every base representation.
