Binary, Octal, Decimal, and Hex Calculator
Add, subtract, multiply, and divide numbers across base 2, 8, 10, and 16, with step-by-step conversion work shown
Run arithmetic — addition, subtraction, multiplication, and division — on numbers in binary, octal, decimal, and hexadecimal, mixing bases freely. The calculator walks through how each input converts to decimal and how the final answer converts back into every base, so you can follow the reasoning instead of just copying the result.

FAQ
- Does division return a quotient and a remainder separately?
- Yes. The calculator uses integer division, the convention throughout computer science, and reports the quotient and the remainder as separate values.
- Are negative numbers supported?
- Yes. Prefix a value with a minus sign (-) and the calculator handles negative inputs and negative results in every base.
- Can this calculator handle decimal values with a fractional part, like 0.5, in base conversions?
- No. This calculator is built specifically for integer arithmetic, so values with a decimal point aren't accepted — it only supports the four basic integer operations plus integer division with a quotient and remainder. If you need to convert a fractional value between bases, you'll need a separate tool designed for real-number base conversion.
