Gematria Calculator
Gematria is a family of letter-to-number systems. A word or phrase is read character by character, each supported letter is assigned a value, and the values are added. This calculator presents that process as a transparent educational tool: choose a method, enter text, and see the total, the number of counted characters, the number of ignored characters, and the method name used for the calculation.
The page is deliberately neutral. Gematria has been used in Jewish textual traditions and has inspired many later recreational and comparative systems, but this calculator does not make mystical, predictive, or interpretive claims. It performs a lookup-and-sum operation. The value is only as meaningful as the alphabet, spelling, and method you choose.
Methods available in this calculator
The English ordinal method gives a = 1, b = 2, c = 3, and so on through z = 26. The conversion method lowercases each Latin letter before lookup, so A and a have the same value. The English gematria method uses the same ordinal sequence multiplied by 6, so a = 6, b = 12, and z = 156. That is the default method.
The Jewish Latin-letter values option uses a specific Latin-letter table stored in the conversion method. It is not a Hebrew transliteration engine; it simply assigns values to a through z according to the table below. The Hebrew standard values option reads Hebrew letters directly, including final forms, and uses the familiar ones, tens, and hundreds pattern.

Exact behavior of the conversion method
The calculator reads the text as JavaScript characters. For English ordinal, English gematria, and Jewish Latin-letter values, each character is lowercased before the table lookup. For Hebrew standard values, the original character is used so Hebrew letters and their final forms can be recognized. If the lookup value is greater than zero, the calculator adds it to the total and increments the counted-character number. Otherwise, the character is ignored.
After the loop, the result panel shows the Total value as the primary result. It also shows Counted characters, Ignored characters, and Method. Ignored characters are calculated as the total number of characters in the input minus the counted characters. If no supported letters are found, the total is still 0, and the note tells you to enter at least one supported letter for the selected method.
Conversion example matching the default
The default input is Omni Calculator and the default method is English gematria. The calculator lowercases the phrase and ignores the space. The ordinal values are o = 15, m = 13, n = 14, i = 9, c = 3, a = 1, l = 12, c = 3, u = 21, l = 12, a = 1, t = 20, o = 15, and r = 18. The ordinal sum is 157. English gematria multiplies each ordinal value by 6, which gives a total of 942.
The result therefore shows Total value: 942. It reports Counted characters: 14, because the fourteen letters are supported, and Ignored characters: 1, because the space has no value. The method line reads English gematria, and the copy text is English gematria value of "Omni Calculator" = 942.
Uses, comparisons, and pitfalls
Gematria appears in discussions of Hebrew texts, manuscript notes, calendars, names, and comparative word studies. Modern English systems are often used recreationally, in puzzles, or to demonstrate how a simple alphabetic encoding works. For other calculator pages that also convert symbols rather than physical quantities, see the Roman numerals converter, the Greek gematria calculator, and the Unicode text converter.
The main pitfall is mixing systems. A word scored with English ordinal cannot be directly compared with a Hebrew word scored with standard Hebrew values unless you explicitly explain why that comparison is being made. Spelling also matters: adding or removing a letter changes the total, while punctuation does not. Finally, no total is unique. Gematria is best handled as a documented numeric convention, not as a substitute for language, history, or context.
