Convert between Binary, Decimal, Hexadecimal, Octal, BCD, and Gray Code instantly. Also convert ASCII text to binary and back.
Numbers can be represented in many different ways depending on the context and the system you are working in. The number 255 in decimal is FF in hexadecimal, 11111111 in binary, and 377 in octal they all represent the same value, just written in different number systems. If you work with computers, electronics, programming, or networking, you switch between these representations constantly. Textaura's number converter handles all of them in one place, instantly.
The converter handles six number systems and one text encoding format. Decimal is the standard base 10 system that everyone uses in everyday life. Binary is the base 2 system that computers use at the hardware level, consisting only of 0s and 1s. Hexadecimal is the base 16 system used in programming, web colors, memory addresses, and many low level computing contexts. Octal is the base 8 system used in Unix file permissions and certain programming contexts. BCD, or Binary Coded Decimal, is a system where each decimal digit is represented by its own four bit binary sequence used in digital clocks, calculators, and industrial systems. Gray Code is a binary numeral system where consecutive values differ by only one bit, which is important in applications like rotary encoders and error minimization in digital circuits. And finally, the tool also converts ASCII text to binary and back, which is useful when working with character encoding.
Computer science students use it constantly when studying for exams or completing assignments that involve number system conversions. Learning to convert between binary and decimal by hand is a useful skill, but when you need to check your work or quickly convert a value mid project, a tool like this is invaluable.
Software developers and programmers use it when working with low level code, bitwise operations, memory addresses, or color values. Hexadecimal shows up everywhere in programming HTML color codes, Unicode code points, memory dumps, and network addresses all use hex. Being able to convert to and from hex instantly without doing the mental arithmetic saves real time.
Electronics and embedded systems engineers work with Gray Code and BCD regularly. Hardware designers dealing with rotary encoders, ADCs, or segment displays need to switch between these representations frequently. Having a tool that handles BCD and Gray Code alongside the standard number systems makes this much easier.
Network engineers work with IP addresses, subnet masks, and port numbers across decimal and binary representations. Understanding how a subnet mask like 255.255.255.0 looks in binary is a fundamental part of networking knowledge, and this tool makes it effortless to verify or explore those conversions.
Every character you type every letter, number, punctuation mark, and space has a corresponding numerical value in the ASCII standard. The letter A is 65 in decimal, which is 01000001 in binary. When you type text into the ASCII conversion section of the tool, it converts each character to its binary representation. And when you paste binary in, it converts it back to readable text. This is useful when studying character encoding, working with data streams, or simply understanding how computers represent text at a fundamental level.
You type or paste a value into any field and all the other representations update instantly. There is no convert button to press as you type, the results appear in real time across all number systems simultaneously. It is fast, accurate, and handles large numbers without any issues. And like everything on Textaura, it is completely free with no account required.
