Why Use This Tool?
Binary, octal, decimal, hexadecimal — four languages for the same number, and computing constantly switches between them. This converter translates any value to all four bases at once, and the arithmetic panel adds, subtracts, multiplies or divides directly in binary.
The '0x' and '0b' prefixes from source code are stripped automatically, so values paste straight in without cleaning.
How It Works
- Enter a value and pick its base — all four representations appear.
- For binary math, enter two binary values and an operation.
- Read the result in both binary and decimal.
Frequently Asked Questions
How do I convert binary to decimal?
Enter the binary value with base 2 selected — each position doubles in value from right to left, and the decimal appears instantly.
How do I add two binary numbers?
Enter both values in the arithmetic panel — the tool converts to decimal, applies the operation, and shows the result back in binary.
Why do programmers use hexadecimal?
One hex digit maps to exactly four binary bits, so hex is a compact readable view of binary — the language of memory addresses and colors.
Tips & Things to Watch
- This math-flavored base converter is separate from text encodings — numbers only here.
- Binary division floors to an integer result.
- Negative results from subtraction display in decimal for clarity.
