Binary to Integer

The Binary to Integer Calculator accepts an binary value and returns the given integer converted to binary.

INSTRUCTIONS: Enter the following:

• (b) This is a base 2 binary

Integer Value:  The calculator returns the integer string equal to the value of the input binary.

The Math / Science

Binary numbers are comprised of zeros (0) and ones (1).  The position of the zero or one indicate the exponent of two added to the value, making binary a base 2 number system

The first value in a binary string is multiplied by 2⁰  (1)
The second value in a binary string is multiplied by 2¹ (2)
The third value in a binary string is multiplied by 2² (4)
The forth value in a binary string is multiplied by 2³ (8), and so on.

In this way, the binary number of 1011 is:

            1 • 2⁰ + 1 • 2¹ + 0 • 2² + 1 • 2³ = 11 in base 10 numbers which we commonly use.

The power of binary is demonstrated in the Pick a Number from 1 to 31 game.  Based on five yes or no questions, you can mathematically determine a number between 1 and 31.  It's binary!  Click on the link and try it.
