ASCII to Decimal Converter
Convert ASCII characters to decimal numbers with accurate results. Get decimal codes quickly for any ASCII text or character with our reliable tool for your needs.
ASCII to Decimal Conversion
ASCII to decimal conversion converts each character's ASCII code (0-255) to its decimal representation using base-10 (standard numeric system).
Formula: decimal = ASCII code
For example:
- Character 'A' has ASCII code 65
- Character 'a' has ASCII code 97
- Character '0' has ASCII code 48
Decimal is the standard number system we use in everyday life, using digits 0-9. Each ASCII character has a unique decimal code from 0 to 255.
ASCII
What is ASCII?
ASCII (American Standard Code for Information Interchange) is a character encoding standard that uses 7 bits to represent 128 characters, including letters (both uppercase and lowercase), digits, punctuation marks, and control characters. ASCII codes range from 0 to 127, with extended ASCII supporting codes 0-255.
History and Usage
ASCII was developed in the 1960s and became the standard character encoding for computers and communication equipment. It is still widely used today in programming, data transmission, and text processing. Each character in ASCII has a unique numeric code that can be represented in different number systems including decimal, binary, octal, and hexadecimal.
ASCII Character Set
The ASCII character set includes 128 standard characters: control characters (0-31), printable characters (32-126), and the DEL character (127). Extended ASCII (128-255) includes additional characters for international use, currency symbols, and special characters.
Decimal
What is Decimal?
Decimal (base-10) is the standard number system we use in everyday life, using digits 0-9. It is the most familiar number system and is used for counting, mathematics, and representing numeric values. Each position in a decimal number represents a power of 10.
Why Use Decimal?
Decimal is intuitive and easy to understand since it's the number system we learn from childhood. It's used in all aspects of daily life, from counting objects to financial calculations. In computing, decimal is often used for displaying numeric values to users, even though computers internally use binary.
Decimal in Computing
While computers use binary internally, decimal is commonly used for user interfaces, data display, and numeric input. Programming languages often provide decimal number types for precise calculations. ASCII codes are frequently referenced in decimal format, making it easy to understand character encoding.
