Gematria Calculator Guide — English and Hebrew Letter Values

What This Calculator Does

This gematria calculator converts letters into numbers and adds their values. English mode displays English Ordinal, Full Reduction, Reverse Ordinal and Reverse Reduction together. Hebrew mode uses Hebrew Standard, also called Mispar Hechrachi. Select a result row or use the dropdown to inspect individual letter values and the complete alphabet chart.

When to Use It

Use it to check a name or phrase, learn a letter-number mapping, or compare two texts under the same cipher. A numerical match is an arithmetic result, not an interpretation of what those texts mean.

Inputs Explained

• Alphabet: Choose English or Hebrew. Switching retains your text and recalculates it with the new alphabet. Try example loads a phrase appropriate for the selected alphabet.
• Word or phrase: Results update as you type. Each field accepts up to 500 UTF-16 code units, as measured by the browser. English mode accepts A–Z without case distinctions; Hebrew mode counts only the listed Hebrew letters.
• Compare with: An optional second text, with the same length limit. Each result row in the comparison shows both totals and whether they match.
• Ignored characters: Spaces, punctuation, digits and unsupported characters add no value. Unsupported letters, numbers and symbols are listed beside the input. Accented letters are not transliterated: café counts only c, a and f. Empty input or input without supported letters produces a prompt instead of a valid zero result.

The calculator itself does not place entered text in the URL or browser storage. Clear removes both texts while retaining your alphabet and cipher selection.

How the Calculation Works

Let n be an English letter's position, with A=1 through Z=26:

Cipher	Value per letter	Checkpoints
English Ordinal	n	A=1, Z=26
Full Reduction	((n−1) mod 9)+1	I=9, J=1, Z=8
Reverse Ordinal	27−n	A=26, Z=1
Reverse Reduction	((26−n) mod 9)+1	A=8, Z=1

Add the values of all supported letters. Full Reduction reduces each letter before addition; it does not reduce the final sum to one digit or preserve master numbers such as 11, 22 or 33.

Hebrew Standard assigns 1–9, then 10–90, then 100–400 in alphabet order. For example, א=1, י=10, ק=100 and ת=400. Final ך, ם, ן, ף and ץ keep 20, 40, 50, 80 and 90. Vowel and cantillation marks add nothing. English text is not transliterated into Hebrew.

Example

Enter Hello world:

Cipher	Total
English Ordinal	124
Full Reduction	52
Reverse Ordinal	146
Reverse Reduction	47

The Ordinal breakdown is HELLO: 8+5+12+12+15=52 and WORLD: 23+15+18+12+4=72. Together they give 124. As a cross-check, Ordinal plus Reverse Ordinal equals 270, or 27 times the ten supported letters.

In Hebrew mode, שלום gives ש=300, ל=30, ו=6 and ם=40: a total of 376. The pointed spelling שָׁלוֹם also gives 376. חי totals 8+10=18.

To try a comparison, enter ab and ba. Rearranging identical letters preserves all four English sums: 3, 3, 51 and 15 respectively.

How to Understand the Result

Cipher totals represent the whole text. Letter breakdown shows every counted letter. Word totals group text by whitespace and ignore punctuation within each group, so hyphens and apostrophes do not create new word groups. Long letter breakdowns scroll, while all supported letters still contribute to the total.

Expand Alphabet reference to inspect the active cipher's mapping. Compare totals within the same cipher; an Ordinal total and a Reduction total use different rules.

Common Mistakes

Do not confuse a Full Reduction sum with the digital root of the final total. Check the mapping before comparing results from sites using labels such as Jewish or English Gematria: these labels may refer to other ciphers. Digits are ignored here, and choosing Hebrew does not convert Latin text into Hebrew letters.

FAQ

Why do numbers alone produce no result?

Digits are not letters in either supported alphabet. They are ignored, including when mixed with a phrase.

Do matching values mean matching meanings?

No. Even rearranging a word preserves its sum. Equal sums cannot establish shared meanings, relationships or future events.

Are Jewish English, Sumerian or custom ciphers included?

No. This version includes only the four named English ciphers and Hebrew Standard. It does not include a Latin Jewish cipher, Sumerian, Greek or custom mappings.

Notes

The tool provides arithmetic for learning and comparison, not predictions. For traditional background, see Chabad's introduction to gematria. Gematrinator's cipher list provides a reference for English cipher names.

For ordinary arithmetic, use the basic calculator. For numerical expressions, use the expression calculator.
