How to convert from binary to decimal

Binary to Decimal Calculator

For convert from binary to decimal you have to perform the sum of the powers of two of 1's. For example, imagine that we want to convert the binary number 111001 to decimal. The following table shows the correspondence in powers of two that we have to use:

Binary number111001
Power of two252423222120

We now perform the sum of the powers that corresponds to each "1" of the binary number that we want to convert to decimal and we obtain the following operation:

1110012 = 1-25+1-24+1-23+0-22+0-21+1-20 = 57

As you can see, it is quite simple to go from binary to decimal, although thanks to our binary calculatoryou can do it automatically.

How to convert binary to decimal in Excel

You can use Excel to convert from binary to decimal and create your own personal calculator to use whenever you need it.

The only thing you need to keep in mind is that the binary number you enter in the spreadsheet must be cannot be longer than 10 charactersthat is, 10 bits. If you exceed this amount, Excel will result in an error represented by #NUM!

If this limitation is not a problem for you, simply write the following formula to be able to use the function that allows you to convert from binary to decimal in Excel:


Remember that C3 are the coordinates of the cell where the binary number you want to convert to decimal is located. If you have chosen another cell in your spreadsheet, you will have to change them.

If you prefer, you can also write the binary number directly between the parentheses to perform the binary to decimal conversion. In this case, you should write a formula similar to this one:
