Convert Unary Base to Integers

Convert Unary Base to Integers takes lines of 1s and turns them into their integer equivalents. Each 1 represents a single count, so 111 becomes 3, 1 becomes 1, and so on. It’s a quick way to convert unary-style data into standard numbers. You can clean up noisy input, ignore non-unary lines, and even map each line visually to its numeric value.

Everything updates in real time as you type, paste, or import your data. No need to click run the results are always live.

How to Use:

  • Type or paste unary values into the Input Unary Numbers box.
  • Each line should be a string of 1s (e.g., 1111).
  • Or click Choose File to import a supported text file.
  • Choose the Output format:
    • Integer only – outputs just the digit (e.g., 4)
    • Unary → Integer – shows both (e.g., 1111 → 4)
  • Toggle Ignore non-unary lines to skip invalid ones like abc or 101.
  • Toggle Maximize output to expand the result area.
  • The result appears instantly in the Converted Integers box.
  • Use Copy Output to copy, or Export to File to save your result.
  • Click Clear All to reset everything.

What Convert Unary Base to Integers can do:

This tool is useful if you’re working with data in unary format where values are stored as repeated 1s. You can:

  • Quickly count unary strings
  • Convert simplified tally systems into real numbers
  • Parse unary logs or encoded data
  • See the original line and its numeric value side-by-side
  • Strip out anything that doesn’t follow unary formatting

It’s fast, handles large lists, and works entirely in your browser.

Example:

Before:

1
11
111
abc
11a1
1111

Output format: Unary → Integer Ignore non-unary lines: On

After:

1 → 1
11 → 2
111 → 3
1111 → 4

Common Use Cases:

Maybe you’re converting tally-mark input from students, or parsing raw exported data that encodes values using 1s. Or maybe you’re working with simplified data structures for experiments or compression. Whatever the reason, Convert Unary Base to Integers gives you clean, fast conversions and keeps your input readable while doing it.

Useful Tools & Suggestions:

If you’re decoding with Convert Unary Base to Integers, you might also need Convert Integers to Unary Base to go the other way when testing or generating samples. And for more base conversions, Convert Binary Base to Integers gives you a useful contrast in how different bases behave.
