Samantha NicoleThe conversion of 40 hex to bin results in 100000. This means that the hexadecimal number 40, when translated into binary, equals 100000 in binary code.
Hexadecimal is a base-16 numbering system, using digits 0-9 and letters A-F, while binary is a base-2 system, using only 0s and 1s. To convert 40 hex to bin, each hex digit is replaced with its 4-bit binary equivalent, resulting in 100000.
Hex to Binary Conversion
To convert 40 hex to bin, the process involves taking each hexadecimal digit and replacing it with its binary equivalent. Hexadecimal digits range from 0 to F, with each represented by a 4-bit binary number. This method works because 16 (hex base) is a power of 2, making conversion straightforward. For example, the hex digit 4 is 0100 in binary, and 0 is 0000, so 40 hex becomes 0100 0000. Combining these gives 100000 binary.

Conversion Formula
The conversion process uses the formula: binary = decimal value of hex number. First, the hex number is translated into a decimal using parseInt(hex, 16). Then, the decimal number is converted into binary with toString(2). For example, hex 40 equals decimal 64, which is 100000 in binary. Step-by-step: 4 hex = 4×16^1 = 64, 0 hex = 0×16^0 = 0, total 64, binary 100000.
Conversion Example
- Hex number: 1A
- Convert each digit: 1 = 0001, A = 1010
- Combine: 0001 1010
- Decimal conversion: 1×16 + 10 = 26
- Binary: 11010
- Hex number: 7F
- Digits: 7 = 0111, F = 1111
- Combine: 0111 1111
- Decimal: 7×16 + 15 = 127
- Binary: 1111111
- Hex number: 2B
- Digits: 2 = 0010, B = 1011
- Combine: 0010 1011
- Decimal: 2×16 + 11 = 43
- Binary: 101011

Conversion Definitions
Hex
Hex, short for hexadecimal, is a base-16 numbering system using digits 0-9 and letters A-F. It simplifies representing binary data, especially in computing, because each hex digit corresponds to four binary bits, making it easier to read and write large binary numbers concisely.
Bin
Bin, or binary, is a base-2 numeral system consisting of only two digits: 0 and 1. It is the foundation of digital electronics and computing, where each bit represents an off or on state. Binary numbers are often used to encode data in computers and communication systems.
Conversion FAQs
How can I quickly verify the binary value of hex 40 without a calculator?
You can verify it by converting each digit: 4 is 0100, and 0 is 0000. Putting them together results in 010000, which simplifies to 100000 by removing leading zeros. This manual method confirms the binary value without electronic tools.
Is there a difference between converting hex 40 to binary and decimal?
Yes, converting hex 40 to decimal involves interpreting it as 4×16 + 0, which equals 64. To convert to binary, you translate decimal 64 to binary, which is 100000. While conversions are related, they require different steps and understanding of number bases.
Why is each hex digit represented by exactly 4 bits in binary?
This is because hexadecimal has 16 symbols, and 2^4 equals 16. Each hex digit maps perfectly onto 4 binary bits, making conversions straightforward and uniform, especially when working with large binary data in programming and digital systems.
