Number Systems Converter

Convert binary, decimal, octal, hexadecimal, ASCII, and text representations while keeping base notation, prefixes, and digit rules clear.

Base conversion logic is deterministic, but notation details such as prefixes, leading zeroes, and text encoding context should stay labeled.

Common Use Cases

Quick Reference

Task Recommended Tool Why It Helps
Read bits as an integer Binary to Decimal Use place values to interpret a bit pattern.
Write integers as bits Decimal to Binary Check bit width, padding, and powers of two.
Inspect HEX values HEX to Decimal Interpret A-F digits and optional 0x notation.
Compress bit patterns Binary to HEX Group binary digits into four-bit HEX chunks.

How Number System Conversions Work

Number system tools translate the same underlying value between representations such as binary, decimal, octal, and hexadecimal. Each base uses a different digit set and place-value relationship, so the label beside the value is part of the meaning.

When values are used in code, documentation, or protocols, preserve notation details such as 0x prefixes, leading zeroes, and fixed bit width separately from the integer value. A value such as 10 can mean decimal ten, binary two, or hexadecimal sixteen depending on context.

Each base uses different place values. Binary uses powers of 2, decimal uses powers of 10, octal uses powers of 8, and hexadecimal uses powers of 16.

They usually do not change the integer value, but they can communicate fixed width such as one byte, a register field, or a protocol value.

No. Text tools map characters to encoded values, while numeric base converters translate an integer between bases.
