Hexadecimal to Decimal to Octal to Binary Converter

To convert a hexadecimal number to decimal, first convert “A” to 10, “B” to 11, etc. Then, multiply each digit by its corresponding power of 16 and sum the results. Next, convert the decimal number to octal by repeatedly dividing by 8 and noting the remainders. Finally, convert the octal number to binary by representing each octal digit with its 3-bit binary equivalent.

How do you convert hexadecimal to binary octal decimal?

To convert a hexadecimal number to binary, octal, or decimal, follow these steps:

  1. Hexadecimal to Binary: Group each hexadecimal digit (0-F) and convert it to its 4-bit binary equivalent. For example, to convert “3A” to binary:
    • 3 (in hexadecimal) = 0011 (in binary)
    • A (in hexadecimal) = 1010 (in binary) So, “3A” in hexadecimal is “00111010” in binary.
  2. Hexadecimal to Octal: First, convert the hexadecimal number to binary and then group the binary digits into sets of 3. Then, convert each group to its octal equivalent. For example, “3A” in hexadecimal is “00111010” in binary, which can be grouped as “001 110 10.” Then, convert each group to octal:
    • 001 (in binary) = 1 (in octal)
    • 110 (in binary) = 6 (in octal)
    • 10 (in binary) = 2 (in octal) So, “3A” in hexadecimal is “162” in octal.
  3. Hexadecimal to Decimal: Convert each hexadecimal digit to its decimal equivalent, considering the position value. For example, “3A” in hexadecimal can be calculated as follows:
    • 3 (in hexadecimal) = 3 (in decimal)
    • A (in hexadecimal) = 10 (in decimal, because A represents 10 in hexadecimal) So, “3A” in hexadecimal is 3 * 16 + 10 = 58 in decimal.

What is the octal number for 0110010011001101?

To convert binary to octal, group the binary digits into sets of 3, starting from the right, and then convert each group to its octal equivalent.

For “0110010011001101”:

  • 01 100 100 110 011 01
  • Convert each group to octal: 01431305 So, the octal representation of “0110010011001101” is “1431305.”

How to convert hex code to binary?

As mentioned earlier, to convert a hexadecimal number to binary, you simply replace each hexadecimal digit with its 4-bit binary equivalent. For example, if you have the hexadecimal code “1E3A,” you can convert it to binary as follows:

  • 1 (in hexadecimal) = 0001 (in binary)
  • E (in hexadecimal) = 1110 (in binary)
  • 3 (in hexadecimal) = 0011 (in binary)
  • A (in hexadecimal) = 1010 (in binary)

So, “1E3A” in hexadecimal is “0001111000111010” in binary.

How to convert octal to hexadecimal and hexadecimal to octal?

So, the binary number “10001101010001101111” is “8D46F” in hexadecimal.

How do you convert hex to decimal manually?

To convert a hexadecimal number to decimal manually, assign a positional value to each digit in the hexadecimal number, starting from the right and increasing by powers of 16. Then, multiply each digit by its positional value and sum the results.

For example, to convert “1E3A” to decimal:

  • A (rightmost digit) = 10 * 16^0 = 10
  • 3 (next digit to the left) = 3 * 16^1 = 48
  • E = 14 * 16^2 = 3584
  • 1 (leftmost digit) = 1 * 16^3 = 4096

Now, add these values together: 10 + 48 + 3584 + 4096 = 7738

So, “1E3A” in hexadecimal is 7738 in decimal.

What is the shortcut to convert hex to binary?

Is hexadecimal and octal the same?

No, hexadecimal (base-16) and octal (base-8) are not the same. They are different numeral systems with different base values. Hexadecimal uses the digits 0-9 and the letters A-F to represent values from 0 to 15 in each digit position, while octal uses the digits 0-7 to represent values from 0 to 7 in each digit position.

How to convert hex to octal in C?

In C, you can use standard library functions to convert hexadecimal to octal. Here’s an example:

cCopy code

#include <stdio.h> int main() { char hexString[] = "1D7F"; // Replace with your hexadecimal value unsigned int hexValue; sscanf(hexString, "%X", &hexValue); printf("Hexadecimal: %s\n", hexString); printf("Octal: %o\n", hexValue); return 0; }

This code reads a hexadecimal string and converts it to an unsigned integer. Then, it prints the value in octal format.

How can I convert my number to octal?

To convert a decimal number to octal, you can use the following steps:

  1. Divide the decimal number by 8 successively to obtain the remainder at each step.
  2. Write down the remainders in reverse order to get the octal representation.

For example, to convert the decimal number 123 to octal:

  • 123 ÷ 8 = 15 remainder 3
  • 15 ÷ 8 = 1 remainder 7
  • 1 ÷ 8 = 0 remainder 1

Now, write down the remainders in reverse order: 173

So, the decimal number 123 is equal to 173 in octal.

What is the addition of the binary numbers 11011011010 and 010100101?

To add binary numbers, align them by their positions (similar to decimal addition) and perform addition from right to left. Carry over any overflow to the next column.

markdownCopy code

11011011010 + 010100101 -------------- 11100100111

So, the addition of 11011011010 and 010100101 is 11100100111 in binary.

Why 8 in octal is 10?

In octal (base-8) numbering, there are only 8 digits available, which are 0, 1, 2, 3, 4, 5, 6, and 7. When you count beyond 7, you need to use a new digit, just as in decimal (base-10) numbering, you use a new digit when you count beyond 9. In octal, the digit 8 is represented as “10” because it’s one group of 8 with 0 remaining.

What is an illegal octal digit 9 at?

In octal notation, the valid digits are 0 through 7. Therefore, the digit “9” is considered illegal in octal because it exceeds the maximum digit value allowed in this base. Any digit in a number that is larger than 7 in octal is not valid.

Why 9 is not allowed in octal number?

Octal is a base-8 numeral system, which means it uses only 8 distinct digits (0-7). This limitation arises from the nature of octal as a positional numeral system. Each digit’s value is determined by its position within the number and its base, which is 8 in the case of octal.

Allowing the digit “9” in octal would create ambiguity because it would be unclear whether it represents 9 in decimal or a different value in octal. To avoid confusion and maintain consistency within the base-8 system, only the digits 0 through 7 are used in octal notation.

What is 163.875 base 10 in binary?

To convert the decimal number 163.875 to binary:
