Does ordinary sigma-tau count as stigma?
No. Ordinary sigma plus tau is counted as two letters. Only an actual stigma character receives the stigma value.
Miscellaneous calculator
Calculate Greek isopsephy values from direct Greek text, including accent normalization, final sigma and archaic numeral signs.

Enter text and calculate locally. The result appears below the calculator with word subtotals, letter values, ignored characters and privacy-safe actions.
Detected script: greek. Input is calculated locally.
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.
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.
Greek 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.
Greek isopsephy uses Greek letter values. The calculator counts actual stigma, koppa and sampi signs, but ordinary sigma-tau is counted as two letters.
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.
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.
λόγος: λόγος -> Normalized = λογος; isopsephy = 373; ordinal = 62.
ΑΘΗΝΑ: ΑΘΗΝΑ -> Isopsephy = 69; ordinal = 30.
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.
Hebrew and Greek pages use direct script input. Mixed-script input is allowed for comparison, but each method counts only the characters supported by that method.
Equal values mean the arithmetic totals match under a selected method. They do not prove that words, people, events or beliefs are objectively connected.
No. Ordinary sigma plus tau is counted as two letters. Only an actual stigma character receives the stigma value.
Greek accents and breathing marks are removed for lookup, while the underlying Greek letter is counted.
Yes. The calculator runs in the browser and does not create public phrase pages, recent-search feeds or a phrase database.
Standard methods ignore spaces and punctuation. Unicode and custom mappings can count characters differently when selected.
No. Latin, Hebrew and Greek methods count direct input for that script and report unsupported characters.
It proves only that two totals are mathematically equal under the chosen method. It does not prove a hidden or factual connection.
Each method uses a different mapping table. Changing the mapping changes the arithmetic result.
Yes. Share text hides the entered phrase by default and reports only the tool, selected method and totals.
No. It performs arithmetic and provides educational context, not authoritative religious, theological or linguistic interpretation.
Yes. The SVG download is generated locally and escapes result text before writing the file.
A digital root repeatedly sums the decimal digits of a number until one digit remains. It is optional for most gematria methods.
The decoder compares phrases you enter, but NexaCalc does not search or maintain a public phrase database.
