What is a binary converter, and how does this free Nepal tool work?

A binary converter changes numbers between binary, decimal, octal and hexadecimal. Scolar's Binary Converter is a free, browser-only tool for Nepal: type in any base and the other three update automatically. No sign-up, no watermark, nothing uploaded.

Why it is free, with no sign-up and unlimited use

Number bases in Nepali courses

Nepal's BSc CSIT, engineering (IOE) and CEE syllabi teach binary, octal and hexadecimal for digital logic and programming. This tool lets a student in Kathmandu or a rural campus practise conversions offline after the page loads, useful where lab computers are shared.

“A Nepali CS student should not pay an app to convert binary to hex. Type it - free.”

Why use this tool?

Binary uses only 0 and 1; each digit is a power of two.
Hexadecimal (base 16) uses 0 to 9 and A to F, handy for colour and memory addresses.
This tool shows all four bases at once, so you can cross-check your manual work.
