155 in Binary
155 in binary is 10011011. 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 155 in binary. In this article, let us learn how to convert the decimal number 155 to binary.
How to Convert 155 in Binary?
Step 1: Divide 155 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 |
|---|---|
| 155/2 = 77 | 1 |
| 77/2 = 38 | 1 |
| 38/2 = 19 | 0 |
| 19/2 = 9 | 1 |
| 9/2 = 4 | 1 |
| 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 155.
Therefore, the binary equivalent of decimal number 155 is 10011011.

How to Convert 155 to Binary Equivalent?
We can divide 155 by 2 and continue the division till we get 0. Note down the remainder in each step.
- 155 mod 2 = 1 - LSB (Least Significant Bit)
- 77 mod 2 = 1
- 38 mod 2 = 0
- 19 mod 2 = 1
- 9 mod 2 = 1
- 4 mod 2 = 0
- 2 mod 2 = 0
- 1 mod 2 = 1 - MSB (Most Significant Bit)
Write the remainders from MSB to LSB. Therefore, the decimal number 155 in binary can be represented as 10011011.
How Many Bits Does 155 in Binary Have?
