This guide is prepared to simplify the conversion process for you with an easy-to-use online tool. We’ll guide you through every step of using this handy hexadecimal-to-octal converter.
Hexadecimal and Octal Number Systems
Hexadecimal and octal number systems are two different ways to show numbers. Think of them like languages for speaking about numbers. Hexadecimal is also known as base 16. It uses sixteen symbols: 0-9 and then A, where A stands for 10 and F means 15. People often use it on computers because it’s good at showing big binary numbers in smaller forms. Octal is another system called base-8. It only uses eight symbols: the digits from 0 to 7. Also try our Decimal to Octal Calculator for convenient results.
Step-by-step Guide On How to Use The Calculator
Using a hexadecimal to octal converter is easy and quick. Follow these simple steps to change your hex numbers into octals:
- Locate the “Enter Hex Number” field on the converter interface.
- Input your hexadecimal number, like “1A,” into the designated field.
- Double-check the format for a valid hexadecimal entry (0–9 and A–F).
- Find and click ‘Calculate’ or ‘Convert’ to initiate the conversion process.
- Verify the correct hexadecimal number entry to avoid typos or errors.
- Wait for the calculator to process the input and perform the hexadecimal to octal conversion.
- Observe the octal result displayed on the screen; for example, “1A” might convert to “32.”
Examples
Let’s say you have the hexadecimal number 1A3 to convert to octal. You would first enter ‘1A3’ into the calculator. Hit the “Calculate” button next, and presto! The screen shows you ‘503’, which is your octal result.
This tool does all the hard work for you in seconds.
Manual Method For Converting Hexadecimal to Octal Number
- Write down the given decimal number.
- If the given decimal number is less than 8, the octal number is the same.
- If the decimal number is greater than 7, divide the number by 8.
- Note the remainder you get after division.
- Repeat steps 3 and 4 with the quotient until it is less than 8.
- Write the remainder in reverse order (bottom to top).
The resultant is the equivalent octal number to the given decimal number.
For example, to convert the decimal number 127 to octal:
- Divide 127 by 8 to get a quotient of 15 and a remainder of 7.
- Divide 15 by 8 to get a quotient of 1 and a remainder of 7.
- Divide 1 by 8 to get a quotient of 0 and a remainder of 1.
Here’s the process of converting the decimal number 127 to octal presented in tabular form:
| Step | Quotient (Q) | Remainder (R) |
|---|---|---|
| 1 | 127 ÷ 8 = 15 | 7 |
| 2 | 15 ÷ 8 = 1 | 7 |
| 3 | 1 ÷ 8 = 0 | 1 |
This table outlines each step of the division process, showing the quotient and remainder at each stage. The final octal equivalent of the decimal number 127 is obtained by reading the remaining.
Since the quotient is now zero, no more division can be done. So by taking the remainders in reverse order, we get the equivalent octal number. Hence, (127)<sub>10</sub> = (177)<sub>8</sub>. Also, Use our Octal to Decimal Calculator for convenient results.
Conversion Process
Here’s the process:
- Convert Hex to Binary:
- Write down the binary equivalent of each hexadecimal digit.
- Hex: 0 1 2 3 4 5 6 7 8 9 A B C D E F
- Bin: 0000 0001 0010 0011 0100 0101 0110 0111 1000 1001 1010 1011 1100 1101 1110 1111
- Write down the binary equivalent of each hexadecimal digit.
- Group Binary Digits:
- Group the binary digits into groups of 3 (starting from the right).
- Add leading zeros if necessary.
- Convert Binary to Octal:
- Write down the octal equivalent for each group of 3 binary digits.
- Bin: 000 001 010 011 100 101 110 111
- Oct: 0 1 2 3 4 5 6 7
- Write down the octal equivalent for each group of 3 binary digits.
- Combine Octal Digits:
- Combine the octal digits obtained in step 3 to get the final octal equivalent.
Let’s take an example:
Suppose you want to convert the hexadecimal number 1A3 to octal.
- Convert to Binary:
- 1: 0001
- A: 1010
- 3: 0011
- Group Binary Digits:
- 0001 0100 0011
- Convert Binary to Octal:
- 1 4 3
So, the octal equivalent of the hexadecimal number 1A3 is 143.

FAQs
1. Can I use the Hexadecimal to Octal Conversion Calculator for programming tasks?
Absolutely. Programmers often use Hexadecimal to Octal Conversion Calculators to convert hexadecimal representations of numbers into octal format for coding purposes, ensuring accurate numerical values in their programs.
2. How do you use a hex-to-octal conversion table?
You use the table by matching each hexadecimal digit with its corresponding octal value, then putting those values together in order, from most significant digit to least significant digit.
3. Can I convert binary numbers using the hexadecimal method?
Yes! Convert your binary number into a hexadecimal number first, and then change that hex number into an octal one using the conversion table.
4. Is learning about radix important for converting between number systems?
Understanding radix is key because it tells you the base of a number system—like base-10 for decimal numbers or base-16 for hexadecimal—which helps when converting numbers.
5. Will multiplying help me convert a decimal number directly to an octal?
No, multiplying won’t work here. You must first change your decimal into either binary or hexadecimal and then use those forms to get your final octal result.
