How to Convert Letters to Numbers

A letters to numbers converter is a versatile tool that transforms text into numeric codes based on different alphabets and encoding methods. This conversion is useful in various contexts including cryptography, puzzles, educational exercises, data encoding, communication systems, and digital encoding. Our free converter supports multiple alphabets (Latin, Arabic, Hebrew, Greek, and Cyrillic) and seven encoding methods, making it perfect for diverse applications and learning purposes.

The converter works by mapping letters to their corresponding numeric values based on the selected encoding method. You can choose from several encoding methods: A=0 (where A is 0, B is 1, C is 2, etc.), A=1 (where A is 1, B is 2, C is 3, etc.), reversed alphabet (where A is the last position, B is second-to-last, etc.), T9 phone keypad (for Latin letters only, mapping letters to phone keypad numbers), ASCII/Unicode (using character code values), hex ASCII/Unicode (using hexadecimal character codes), or binary ASCII/Unicode (using binary character codes). Each method serves different purposes and is useful for various encoding and cryptography tasks.

Letters to numbers conversion is useful for: encoding text messages and ciphers, solving puzzles and riddles, educational exercises in cryptography and encoding, converting text data to numeric format, working with different writing systems, learning alphabet positions and relationships, encoding and decoding messages, understanding letter-number mappings, creating numeric codes for communication, and digital data encoding. The converter handles entire text strings, automatically converts each character to its corresponding number based on your selected alphabet and encoding method, and displays the results separated by spaces for easy reading.

Our letters to numbers converter works automatically as you type. Here's how to convert letters to numbers with our tool: (1) Enter your text - Simply type or paste your letters into the textbox. (2) Select the encoding method - Choose between A1Z26 cipher (A=1), zero-based indexing A0Z25 (A=0), reversed alphabet, T9 phone keypad, ASCII, hex ASCII, or binary ASCII. (3) Choose the alphabet type - Pick from the supported alphabets: Latin, Arabic, Hebrew, Greek, or Cyrillic. (4) Read the encoded text - The result appears instantly below, and you can copy it with a single click. No registration required. The tool supports all characters, handles spaces as 0 in alphabet-based methods, and works with multiple alphabets for diverse encoding needs.

Example:

Input: 'F s' with Latin alphabet and A=0 method generates: '5 18' (F is the 6th letter, so 5 in 0-based indexing; s is the 19th letter, so 18). Input: 'HELLO' with Latin alphabet and A=1 method generates: '8 5 12 12 15'. Input: 'ABC' with Latin alphabet and reversed method generates: '25 24 23'. Input: 'HELLO' with T9 method generates: '4 3 5 5 6'. Input: 'A' with ASCII method generates: '65'. Input: 'A' with hex method generates: '41'. Input: 'A' with binary method generates: '01000001'. The converter handles all characters, automatically converts each to its corresponding number, and displays the results separated by spaces.

Frequently Asked Questions

A letters to numbers converter is a tool that transforms text into numeric codes based on alphabet positions or character encoding. It supports different alphabets (Latin, Arabic, Hebrew, Greek, Cyrillic) and multiple encoding methods (A=0, A=1, reversed alphabet, T9 keypad, ASCII, hex, binary), making it useful for cryptography, puzzles, education, and various encoding/decoding tasks.
A=0 method means the first letter (A) corresponds to number 0, the second letter (B) to number 1, and so on. A=1 method means the first letter (A) corresponds to number 1, the second letter (B) to number 2, and so on. For example, with Latin alphabet: A=0 method: A→0, B→1, Z→25. A=1 method: A→1, B→2, Z→26.
The reversed alphabet method assigns numbers in reverse order: the last letter gets the first number, and the first letter gets the last number. For example, with Latin alphabet (26 letters): A→25, B→24, ..., Z→0. This creates a simple cipher where letters are encoded in reverse alphabetical order.
T9 phone keypad encoding maps letters to their corresponding phone keypad numbers. For example: A, B, C → 2; D, E, F → 3; G, H, I → 4; J, K, L → 5; M, N, O → 6; P, Q, R, S → 7; T, U, V → 8; W, X, Y, Z → 9. This method only works with Latin letters. Non-letter characters are kept as-is.
ASCII encoding uses the decimal character code (e.g., A = 65). Hex encoding uses hexadecimal representation of the character code (e.g., A = 41 in hex). Binary encoding uses binary representation of the character code (e.g., A = 01000001 in binary). All three methods work with any character (not just letters) and use Unicode character codes, making them universal encoding methods.
