Samantha NicoleThe binary number 10101 converts to the text “21”.
To convert binary 10101 to text, first interpret 10101 as a binary value, which equals 21 in decimal. Since ASCII code 21 is a non-printable control character, the result is often represented as the number 21. This process involves converting the binary to decimal, then mapping that value to its ASCII character.

Conversion Formula
To get text from binary, the process involves two steps: first, convert the binary number to decimal by summing each bit multiplied by 2 raised to its position power; second, map the decimal to its ASCII character. For example, binary 10101 is calculated as (1×2^4) + (0×2^3) + (1×2^2) + (0×2^1) + (1×2^0) = 16 + 0 + 4 + 0 + 1 = 21, which corresponds to ASCII code 21.
Conversion Example
- Binary: 11010
- Step 1: Write down the binary digits: 1 1 0 1 0
- Step 2: Assign positional values: (1×2^4) + (1×2^3) + (0×2^2) + (1×2^1) + (0×2^0)
- Step 3: Calculate each: 16 + 8 + 0 + 2 + 0 = 26
- Step 4: Convert decimal 26 to ASCII: which is the character SUB (non-printable)
- Binary: 11111
- Step 1: Digits: 1 1 1 1 1
- Step 2: Positional values: (1×2^4) + (1×2^3) + (1×2^2) + (1×2^1) + (1×2^0)
- Step 3: Sum: 16 + 8 + 4 + 2 + 1 = 31
- Step 4: Decimal 31 in ASCII: unit separator (non-printable)
- Binary: 10000
- Step 1: Digits: 1 0 0 0 0
- Step 2: Positional values: (1×2^4) + 0 + 0 + 0 + 0
- Step 3: Sum: 16
- Step 4: ASCII 16 corresponds to a data link escape character (non-printable)

Conversion Definitions
Binary
Binary is a numbering system that uses only two digits, 0 and 1, to represent data. It is the foundation of digital computing, where each binary digit (bit) encodes a state like off/on or false/true, enabling computers to perform complex operations through simple binary signals.
Text
Text refers to written characters, symbols, or words represented through encoding schemes like ASCII, where each character is assigned a specific numerical value. Text is the human-readable form of data that computers interpret and display for user interaction.
Conversion FAQs
What ASCII character does binary 10101 represent?
Binary 10101 converts to decimal 21, which is a control character called “Device Control 1” in ASCII, not a visible symbol. It’s used for communications control rather than display purposes.
Can I convert binary 10101 to a hexadecimal value?
Yes, binary 10101 equals hexadecimal 0x15. To convert, divide the binary into two parts or directly translate: 10101 in binary is 21 in decimal, which equals 15 in hexadecimal.
Is binary 10101 a common code for any specific symbol?
Binary 10101 corresponds to ASCII decimal 21, which is not a common printable symbol but a control code used in data transmission protocols. It does not represent a standard letter or number in text.
