The binary number 10101 converts to the text “21”.
To convert binary 10101 to text, first, split the binary into 8-bit groups or ASCII code points. In this case, 10101 represents the decimal value 21, which corresponds to the ASCII control character “NAK”. However, if considering only the value, it’s decimal 21, which is often represented as a number in text form.
Conversion Result
The binary number 10101 equals the decimal 21, which can be interpreted as the character “NAK” in ASCII or simply the number 21 in text form.

Conversion Formula
The conversion from binary to text relies on calculating the decimal equivalent of the binary number, then translating that decimal to its corresponding ASCII character. The formula: decimal = (b0×2^0) + (b1×2^1) + … + (bn×2^n). For example, binary 10101: 1×2^4 + 0×2^3 + 1×2^2 + 0×2^1 + 1×2^0 = 16 + 0 + 4 + 0 + 1 = 21.
This works because each binary digit (bit) represents a power of two, and summing these powers gives the decimal value, which directly correlates to ASCII characters in text encoding.
Conversion Example
- Binary: 11010
- Step 1: Break into bits: 1 1 0 1 0
- Step 2: Calculate decimal: 1×2^4 + 1×2^3 + 0×2^2 + 1×2^1 + 0×2^0
- Step 3: Compute: 16 + 8 + 0 + 2 + 0 = 26
- Step 4: Convert to ASCII: decimal 26 is “SUB” control character
- Binary: 10000
- Step 1: Bits: 1 0 0 0 0
- Step 2: Decimal: 1×2^4 + 0 + 0 + 0 + 0 = 16
- Step 3: ASCII character: decimal 16 is “DLE” control character
- Binary: 11111
- Step 1: Bits: 1 1 1 1 1
- Step 2: Decimal: 16 + 8 + 4 + 2 + 1 = 31
- Step 3: ASCII character: decimal 31 is “US” control character

Conversion Definitions
Binary
Binary is a base-2 numeral system uses only two digits, 0 and 1, to represent data in digital electronics. Every bit in binary encodes a power of two, making it fundamental in computer systems for data storage and processing.
Text
Text refers to written or printed words and characters interpreted by computers using encoding standards like ASCII or Unicode, where each symbol is represented by a specific binary code, enabling digital communication of human language.
Conversion FAQs
How can I convert binary 10101 to decimal manually?
To convert binary 10101 to decimal, multiply each bit by 2 raised to its position index, starting from 0 on the right. Then sum all the products. For 10101: (1×2^4) + (0×2^3) + (1×2^2) + (0×2^1) + (1×2^0) = 16 + 0 + 4 + 0 + 1 = 21.
What is the ASCII character for binary 10101?
Binary 10101 corresponds to the decimal 21, which in ASCII is a control character called “NAK” (Negative Acknowledgement). It’s not a printable character, but rather used for communication control in data streams.
Can binary 10101 be a part of Unicode encoding?
Yes, binary 10101 (decimal 21) can be part of Unicode, specifically within the ASCII range, representing the same control code. Unicode extends ASCII, so common ASCII codes are directly compatible within Unicode standards.
Why does converting binary 10101 yield the number 21?
Because each binary digit’s position represents a power of two, summing these gives the decimal value. For 10101: 1×16 + 0×8 + 1×4 + 0×2 + 1×1 = 21, which is the decimal equivalent of the binary number.
Is there a quick way to convert binary to text without manual calculations?
Yes, using programming languages or online converters can instantly translate binary numbers like 10101 into their text or ASCII characters, saving time and reducing errors in manual math.
