The 28 letters
The 28 letters, their numbers, elements and planets — the table everything else uses.
Read across for a letter's value, its element and its planet. The checks at the bottom prove the calculator against numbers you may already know.
Use the checks at the foot of the table to test any other calculator against this one. If another tool disagrees on بسم اللہ الرحمن الرحیم or اللہ, the difference is almost always a different spelling convention or a different set of letter values — not one of you being broken.
