What the Gematria Calculator calculates
Computes the gematria value of Hebrew or Latin-alphabet text under a named classical cipher, showing the value assigned to every letter.
How to use this Gematria Calculator
Enter Word or phrase and Cipher. Gematria value updates as you type, and “Use a worked example” loads checked figures you can adjust. Change one figure at a time to see what drives the result.
How the result is worked out
Open “How this is worked out” beside the result for the step-by-step calculation behind Gematria value, Cipher used and Letters scored.
The method follows Gematria, The Jewish Encyclopedia (1901-1906), vol. V, Gershom Scholem, "Gematria", Encyclopaedia Judaica, 2nd edition, vol. 7 and The Unicode Standard, Hebrew block U+0590-U+05FF.
Chai (חי) is the classic gematria of 18 example
With Word or phrase: חי, Cipher: hebrew_standard, the calculator returns Gematria value: 18, Letters scored: 2. This example is checked against an independent source in the test suite.
What you can compare
Change one input at a time to see how it affects Gematria value, Cipher used and Letters scored. The inputs you can vary are Word or phrase and Cipher.
Understanding Gematria value, Cipher used and Letters scored
Gematria is a traditional interpretive practice, not a measurement. Different ciphers give different totals for the same text, so a value is meaningful only alongside the named cipher used to produce it.
Results are general information, not financial, tax, legal, medical or engineering advice. Check any decision that matters with a qualified professional.
