1. What is Words to Numbers Conversion?

Words to numbers conversion is the process of translating written number words (like "twenty-five") into their numerical equivalent (25). This calculator uses a dictionary lookup approach to accurately convert English number words to digits.

2. How Does the Calculator Work?

The calculator processes input text through these steps:

1. Converts input to lowercase for consistent processing
2. Splits the text into individual words
3. Matches each word against a predefined number dictionary
4. Applies mathematical rules for compound numbers (like "twenty-five")
5. Handles multipliers like "hundred", "thousand", and "million"
6. Combines all components to produce the final numerical result

3. Importance of Word-to-Number Conversion

Details: This conversion is essential for natural language processing, data entry automation, accessibility tools, and educational applications. It helps bridge the gap between human-readable text and machine-processable numerical data.

4. Using the Calculator
