In this comprehensive guide, we will explore the BIN2OCT formula in Excel. The BIN2OCT function is used to convert a binary number to an octal number. Binary numbers are base-2 numbers, which use only 0 and 1, while octal numbers are base-8 numbers, using digits from 0 to 7. This function is particularly useful when working with different number systems, such as in computer programming or digital electronics.
The syntax for the BIN2OCT function in Excel is as follows:
- binary_number (required) – This is the binary number you want to convert to an octal number. It can be entered as a string of 0s and 1s, or as a reference to a cell containing the binary number.
- places (optional) – This is the number of digits you want to display in the resulting octal number. If omitted, Excel will display the minimum number of digits required to represent the octal number. If the specified number of places is less than the minimum required, Excel will display the minimum number of digits.
Let’s look at some examples of using the BIN2OCT function in Excel:
- Basic Conversion: To convert the binary number 101101 to an octal number, you can use the formula =BIN2OCT(“101101”). The result will be 55, as the binary number 101101 is equal to the octal number 55.
- Using Cell References: If you have the binary number 1101101 in cell A1, you can use the formula =BIN2OCT(A1) to convert it to an octal number. The result will be 155, as the binary number 1101101 is equal to the octal number 155.
- Specifying Places: To convert the binary number 1010 to an octal number with a minimum of 4 digits, you can use the formula =BIN2OCT(“1010”, 4). The result will be 0012, as the binary number 1010 is equal to the octal number 12, and we specified that we want at least 4 digits in the result.
BIN2OCT Tips & Tricks
Here are some tips and tricks to help you get the most out of the BIN2OCT function in Excel:
- Remember that the BIN2OCT function can only handle binary numbers up to 10 digits in length. If you need to convert a binary number with more than 10 digits, you will need to use a different method.
- If you want to convert an octal number back to a binary number, you can use the OCT2BIN function in Excel.
- When working with binary and octal numbers, it can be helpful to use Excel’s formatting options to display the numbers with a fixed number of digits. For example, you can use the custom number format “0000” to display a 4-digit octal number with leading zeros.
Common Mistakes When Using BIN2OCT
Here are some common mistakes to avoid when using the BIN2OCT function in Excel:
- Entering a binary number with more than 10 digits will result in a #NUM! error. Make sure your binary numbers are within the supported range.
- Entering a binary number with characters other than 0 and 1 will result in a #NUM! error. Double-check your binary numbers to ensure they only contain 0s and 1s.
- Forgetting to include the optional places argument when you want to display a specific number of digits in the resulting octal number. If you want to display a fixed number of digits, make sure to include the places argument in your formula.
Why Isn’t My BIN2OCT Working?
If you’re having trouble with the BIN2OCT function in Excel, here are some common issues and their solutions:
- Error #NUM!: This error occurs when the binary_number argument contains more than 10 digits or contains characters other than 0 and 1. Double-check your binary number to ensure it is within the supported range and only contains 0s and 1s.
- Error #VALUE!: This error occurs when the binary_number argument is not entered as a string or a cell reference. Make sure you enter the binary number as a string (enclosed in double quotes) or as a reference to a cell containing the binary number.
- Incorrect Result: If you’re getting an unexpected result from the BIN2OCT function, double-check your formula and input values to ensure they are correct. Also, make sure you’re using the correct function for the number system conversion you want to perform.

Here are some related formulae that you might find useful when working with binary and octal numbers in Excel:
- OCT2BIN: This function converts an octal number to a binary number. The syntax is =OCT2BIN(octal_number, [places]).
- BIN2DEC: This function converts a binary number to a decimal number. The syntax is =BIN2DEC(binary_number).
- DEC2BIN: This function converts a decimal number to a binary number. The syntax is =DEC2BIN(decimal_number, [places]).
- OCT2DEC: This function converts an octal number to a decimal number. The syntax is =OCT2DEC(octal_number).
- DEC2OCT: This function converts a decimal number to an octal number. The syntax is =DEC2OCT(decimal_number, [places]).
