1111 in binary is 10001010111. Unlike the decimal number system where we use the digits 0 to 9 to represent a number, in a binary system, we use only 2 digits that are 0 and 1 (bits). We have used 11 bits to represent 1111 in binary. In this article, let us learn how to convert the decimal number 1111 to binary.
How to Convert 1111 in Binary?
Step 1: Divide 1111 by 2. Use the integer quotient obtained in this step as the dividend for the next step. Repeat the process until the quotient becomes 0.
| Dividend | Remainder |
|---|---|
| 1111/2 = 555 | 1 |
| 555/2 = 277 | 1 |
| 277/2 = 138 | 1 |
| 138/2 = 69 | 0 |
| 69/2 = 34 | 1 |
| 34/2 = 17 | 0 |
| 17/2 = 8 | 1 |
| 8/2 = 4 | 0 |
| 4/2 = 2 | 0 |
| 2/2 = 1 | 0 |
| 1/2 = 0 | 1 |
Step 2: Write the remainder from bottom to top i.e. in the reverse chronological order. This will give the binary equivalent of 1111.
Therefore, the binary equivalent of decimal number 1111 is 10001010111.

Find the Value of 3 × 1111 in Binary Form.
We know that 1111 in binary is 10001010111 and 3 is 11. Using the binary multiplication rules (0 × 0 = 0; 0 × 1 = 0 ; 1 × 0 = 0 and 1 × 1 = 1), we can multiply 10001010111 × 11 = 110100000101 which is 3333 in the decimal number system. [1111 × 3 = 3333]
What is the Binary Equivalent of 1111 + 68?
1111 in binary number system is 10001010111 and 68 is 1000100. We can add the binary equivalent of 1111 and 68 using binary addition rules [0 + 0 = 0, 0 + 1 = 1, 1 + 1 = 10 note that 1 is a carry over to the next bit]. Therefore, (10001010111)₂ + (1000100)₂ = (10010011011)₂ which is nothing but 1179.
