Base Number System

How the Base Number System works

Converts an integer among binary, octal, decimal and hexadecimal.

Formula / method. Interpret the input in the source radix, then emit it in the target radix. 0xFF = 255 = 0377 = 11111111₂.

When to use it. Use it for a bitmask, a colour, or a memory address.

How to run a comparison

1. Open Base Number System from Home search, the Developer & Tech Tools hub, or this URL.
2. Copy amounts, rates or dates from a document you already have — not a round marketing figure.
3. Read the headline result and any breakdown (schedule, slabs, or intermediate rows).
4. Change one input at a time so you can see what actually moves the answer.
5. Cross-check with a related calculator below, then confirm statutory rates before you act.

Nothing you type is uploaded for server-side processing. Save or screenshot an output if you need it later; we do not keep a server-side history.

Notes and assumptions

Integers only. Fractional bases and one’s-complement are out of scope.

Results are estimates for education and planning only. They are not financial, tax, medical, or legal advice. Slabs, scheme rates and product terms change; verify against official notifications or a qualified professional before acting.
