Simple Gematria Calculator

NexaCalc stores each mapping once in the shared engine and renders the active table below so totals can be checked by hand. Custom word-value mappings are validated in the calculator before use.

• Text is treated as plain text and never executed as markup.
• Latin diacritics, Hebrew marks and Greek accents are normalized according to the selected options.
• Whitespace and punctuation have zero value for the standard letter-value methods.
• Equal totals are arithmetic matches only, not evidence of prediction, proof or authority.
• Share text hides the entered phrase, name or date by default.

Simple Gematria Calculator converts text into numeric totals using selected letter-value mappings. The calculation is arithmetic only: each counted character receives a value and the values are summed.

Simple gematria is the direct alphabet-position method: A equals 1 and Z equals 26. It is useful as a plain arithmetic word-value tool.

Enter a word, phrase, name or comparison set, choose the method options, then calculate. The result card appears below the input card with totals, word subtotals, letter contributions and ignored characters.

• Use direct script input instead of automatic transliteration.
• Review the method label before comparing values.
• Use copy, print, share or local SVG download without creating public result pages.

Each method uses a fixed mapping table. Latin methods count Latin letters, Hebrew methods count Hebrew letters, Greek methods count Greek letters, and Unicode code-point mode sums technical code point values.

Latin input can normalize accents to base letters, Hebrew input strips niqqud and cantillation marks, and Greek input removes accents and breathing marks for lookup. Unsupported scripts are reported instead of transliterated.

The contribution table shows every counted letter, its normalized form, its value and the running total. Punctuation and spaces are ignored for letter-value methods unless a custom mapping explicitly counts them.

HELLO: HELLO -> H=8, E=5, L=12, L=12, O=15; total = 52; reverse ordinal = 83; digital root = 7.

Alphabet checksum: ABCDEFGHIJKLMNOPQRSTUVWXYZ -> A through Z simple total = 351.

Different methods answer different arithmetic questions. Equal totals across methods or phrases do not prove an objective relationship, and method names should not be merged together.

The page includes the active mapping table so the total can be checked by hand. Long tables remain scrollable on smaller screens.

Gematria, isopsephy, arithmancy and numerology have appeared in different historical and cultural settings. NexaCalc separates historical letter-value conventions from modern online ciphers and recreational systems.

A calculator can show arithmetic totals, but it cannot validate a belief, interpretation, prediction, identity claim or religious conclusion. Treat equal values as equal numbers under a chosen mapping.

Calculations run in the browser. NexaCalc does not store entered phrases, does not publish recent searches and does not create indexable result pages.

Gematria and letter-value systems provide mathematical totals based on selected mappings. Equal values do not prove that words, people or events are objectively connected.
