Frequently asked questions

How do I use this calculator?

Enter text. The result updates automatically. Use Reset to restore the example values.

What method does it use?

Apply the stated character mapping; preserve unsupported characters.. Uses the explicitly defined A→4, E→3, I→1, O→0, S→5, T→7 mapping; other conventions differ.

Why might a rounded result differ?

The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.

Are my inputs saved online?

No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
