What is Gematria?
In Greek and Hebrew each letter of the alphabet doubles as a number. This is very similar to Roman numerals which are still used in English today. Gematria is the practice of calculating the numeric equivalent of words and phrases by adding up the numbers associated with each letter. Technically, Gematria refers to calculation in Hebrew while Isopsephy is the Greek equivalent.
The English alphabet doesn't normally carry numeric values but this practice has been carried into English using numbering systems similar to the ancient languages. This has become known as English Gematria.

Words and names can be typed directly into the text box but it's important to note that each numbering system expects letters from the respective language. Hebrew for Hebrew systems, Greek for Greek systems, and English for English systems. The one exception is Greek Beta Code which is a represention of Greek using the English alphabet and various symbols. Usage of Greek Beta Code can be found on Studylight.org while biblos.com offers the original Hebrew and Greek of the Bible for copy and paste into the calculator.
The built in keyboard () displays the values associated with each letter and can also be used to input letters for each system. A brief description of each numbering system and a link to further information can be found by clicking on the help icon (). After calculation the save button will submit a value to be considered for inclusion in the Gematria database.
Numbers carry meanings based on the words associated with them, but those meanings are often contradictory and ambiguous. Ultimately the significance assigned to a number will be somewhat personal based on one's beliefs and preconceptions. To get started you can consult Numbers, Symbolism and Properties on this site or another good Gematria reference. Finally, a word of caution. The study of Gematria is interesting and can even be enlightening when studying the Bible, but for daily life it's no substitute for a genuine faith in God and the Savior Jesus Christ.
