255 in Binary
255 in binary is 11111111. 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 8 bits to represent 255 in binary. In this article, let us learn how to convert the decimal number 255 to binary.
How to Convert 255 in Binary?
Step 1: Divide 255 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 |
|---|---|
| 255/2 = 127 | 1 |
| 127/2 = 63 | 1 |
| 63/2 = 31 | 1 |
| 31/2 = 15 | 1 |
| 15/2 = 7 | 1 |
| 7/2 = 3 | 1 |
| 3/2 = 1 | 1 |
| 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 255.
Therefore, the binary equivalent of decimal number 255 is 11111111.
