The Binary Converter lets you instantly convert numbers between four number bases: binary (base 2), decimal (base 10), hexadecimal (base 16), and octal (base 8). Type in any of the four fields and all others update automatically. Essential for computer science students, programmers working with memory addresses and bitwise operations, hardware engineers, and anyone learning digital electronics fundamentals. Includes a quick reference for common conversions and the relationship between bits, bytes, and hex values.
The File Size Converter lets you convert between all common digital storage units: bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB). Choose between binary (base-2: 1 KB = 1,024 bytes) and decimal (base-10 SI: 1 KB = 1,000 bytes) calculation modes, since storage manufacturers use decimal while operating systems use binary — which is why a "1 TB" hard drive shows up as about 931 GB in Windows or macOS. Useful for understanding storage requirements, comparing device capacities, estimating upload/download times, and database storage planning.
