The binary number 1001 converts to the text character “9”.
To understand this conversion, we interpret 1001 as a binary number, which is a base-2 numeral system. Each binary digit (bit) contributes to the total value based on its position, with the rightmost being the least significant. Converting binary 1001 involves summing powers of 2 for each ‘1’ bit, resulting in the decimal value 9, which corresponds to the character “9” in ASCII.

Conversion Formula
The conversion from binary to text is based on the formula: decimal = Σ (bit * 2^position). For each binary digit, multiply the bit (0 or 1) by 2 raised to its position index, starting from 0 on the right. Summing these gives the decimal value which maps to a character. For example, binary 1001: (1*2^3) + (0*2^2) + (0*2^1) + (1*2^0) = 8 + 0 + 0 + 1 = 9. ASCII code 9 is the character “9”.
Conversion Example
- Binary 1010 to decimal:
- Bits: 1 0 1 0
- Position: 3 2 1 0
- Calculation: (1*2^3) + (0*2^2) + (1*2^1) + (0*2^0) = 8 + 0 + 2 + 0 = 10
- ASCII 10 is a line feed (new line character)
- Binary 1101 to decimal:
- Bits: 1 1 0 1
- Position: 3 2 1 0
- Calculation: (1*8) + (1*4) + (0*2) + (1*1) = 8 + 4 + 0 + 1 = 13
- ASCII 13 is a carriage return
- Binary 0110 to decimal:
- Bits: 0 1 1 0
- Position: 3 2 1 0
- Calculation: (0*8) + (1*4) + (1*2) + (0*1) = 0 + 4 + 2 + 0 = 6
- ASCII 6 is an acknowledgment character

Conversion Definitions
Binary
Binary is a numeral system that uses only two symbols, 0 and 1, representing off/on states in digital electronics. Each position signifies a power of 2, enabling the encoding of data and instructions in computers, making it fundamental for digital communication.
Text
Text refers to written or printed characters that form words, sentences, and information, stored digitally as sequences of binary codes. Each character typically corresponds to a numerical code like ASCII, allowing computers to process, display, and transmit human-readable data.
Conversion FAQs
How do I convert a binary number like 1001 into a character in ASCII?
To convert binary 1001 to ASCII, first transform it into decimal (which is 9). Then, find the ASCII character associated with decimal 9, which is a tab or control character. For printable characters, use binary values that correspond to visible symbols.
Why does binary 1001 convert to the digit “9”?
This is because in ASCII, the decimal value 57 represents the character “9”. But binary 1001 equals decimal 9, which is a control character, not the digit “9”. To get the character “9”, the binary should be 00111001. The binary 1001 is a different character, mostly a control code.
Can I use this conversion method for larger binary numbers?
Yes, this method works for larger binary numbers as well. Just convert the binary string into a decimal number by summing powers of 2 for each ‘1’ bit, and then find the text character associated with that decimal in ASCII or Unicode tables. Be aware of character encoding limits.
What is the difference between binary and hexadecimal in text encoding?
Binary uses only 0s and 1s, while hexadecimal uses 0-9 and A-F to represent data more compactly. Both are used in encoding text, but hexadecimal is often easier for humans to read and write, while binary is the fundamental machine language for computers.
