What is the Hebrew numeric value of Arabic letter w?

There's no direct equivalent of the Arabic letter و (waw) in Hebrew numerology (Gematria). Hebrew Gematria uses the Hebrew alphabet and assigns numerical values to its letters. Arabic letters have their own numerical system. To find a Hebrew numerical equivalent, you would need to transliterate the Arabic word containing the و into Hebrew and *then* calculate the Gematria value of that Hebrew transliteration. The resulting value would depend entirely on the transliteration used.
