Step-by-Step
How to Convert Bytes to Bits
Converting a byte to bits is incredibly simple once you know the core rule.
The 1 Byte is 8 Bits Rule
A bit is the absolute smallest unit of digital information. A byte is a slightly larger grouping. Because there are exactly 8 bits in a byte, the math is always straightforward.
To convert bytes into bits, simply multiply the number of bytes by 8.
How to Turn Bytes into Bits — Step by Step
Write down your bytes
Start with the number of bytes you want to convert. For example, let's say you have 16 bytes.
Multiply by 8
Take your number and multiply it by 8. In this case, 16 × 8 gives you 128.
Read your new value
You now know that 16 bytes equals exactly 128 bits. The conversion works the same way for any amount.
Bytes vs Bits
Understanding Bits in a Byte
People frequently ask: a byte is how many bits? In almost all modern computing, 1 byte is 8 bits. While they measure the same type of digital data, we use them for different things.
We typically measure internet speeds and network transfers using bits (like Mbps). On the other hand, we use bytes to measure file sizes and hard drive storage space (like Megabytes or Gigabytes).
Whenever you need to switch between the two, just remember how many bit in a byte there are, and multiply your total by 8.
Worked Examples
Sample Bytes to Bits Calculations
Here is how the math breaks down for the most common byte to bit conversions.
1 byte is how many bits?
Since 1 × 8 = 8, there are exactly 8 bits in one byte.
2 bytes to bits
Multiply 2 by 8. Two bytes give you exactly 16 bits.
8 bytes to bits
Take 8 and multiply by 8. Eight bytes equals 64 bits.
16 bytes to bits
Multiply 16 by 8. Sixteen bytes equals 128 bits.
128 bytes to bits
Take 128 and multiply by 8. You get exactly 1024 bits.
256 bytes to bits
Multiply 256 by 8. That leaves you with 2048 bits.
1024 bytes to bits
Take 1024 and multiply by 8. This standard kilobyte size gives you 8192 bits.
2048 bytes to bits
Multiply 2048 by 8. This equals 16384 bits.
