Select a letter to compare its value across map systems.
How to use number maps
Keep the letter value tables open when you want the forward letter→value chart.
Pick a named cipher
Ordinal, Full Reduction, Jewish, Reverse, Sumerian, Hebrew Hechrachi, Siduri, Gadol, or Greek — each tab is a different letter-to-number map.
Enter a value
The explorer lists every letter that equals that number in the active map. Empty means no letter carries that value — not a missing dictionary.
Compare one letter across maps
Select a result letter to see how its value changes under other systems. Sofit forms appear where the chart includes them.
Worked examples
Number maps run the usual math backwards: you start from a value and see which letters carry it. For the forward direction, see how a letter total is built.
Full Reduction value 1· A · J · S
- System
- Full Reduction (1–9 cycle)
- Letters
- A=1, J=1, S=1 — three letters share the same Full Reduction place.
Ordinal value 12· L
- System
- English Ordinal
- Letters
- Only L equals 12 (A=1…Z=26).
Hechrachi value 40· מ · ם
- System
- Mispar Hechrachi
- Letters
- Mem and final mem both count as 40 under Hechrachi.
Chart vs number maps vs decoder
Number Maps (this page)
Value → letters for a named cipher, plus cross-system letter compare. Interactive reverse of a single glyph’s place in the map.
Gematria Chart
Static letter → value tables for bookmarking and print. Full A→n / aleph→tav lists without typing a number.
Use gematria chart when that tool fits the question better.
Gematria Decoder
Value → indexed English words. Use when the question is which words share a total, not which letters equal a number.
Use Open decoder when that tool fits the question better.
When you need whole words that equal a value, not single letters, use the reverse gematria lookup instead.

Frequently asked questions
What is a gematria number map?
A number map answers which letters equal a given value in a named cipher. It is the reverse of looking up one letter on a chart — not a word decoder and not a full-word calculator.How is this different from the Gematria Chart?
The chart lists letter → value tables for print and quick A→n lookup. Number Maps takes a value first and lists matching letters, and can compare one letter across systems.How is this different from the Gematria Decoder?
The decoder searches an English word index for spellings that sum to a number. Number Maps only returns letters from the cipher charts — never dictionary words.Why can several letters share one value?
Some maps fold the alphabet (Full Reduction 1–9) or assign the same Hechrachi value to a letter and its sofit form. Shared values are map design, not a meaning claim.Are AtBash, AlBam, and Mispar Katan included?
No. Those methods substitute or reduce before summing and are not flat letter→value charts on this page. Use Advanced Methods for those procedures.
