Why Convert Bytes to Bits?

Converting between bytes (B) and bits (b) is one of the most common digital storage conversions. Whether for engineering, cooking, travel, or science, knowing how to quickly convert B to b saves time and prevents errors.

Digital storage conversions (B to b) are essential for IT professionals, content creators, and everyday computer users. Understanding the difference between bits and bytes is crucial when calculating internet speeds versus file sizes. Photographers and video editors need to convert terabytes and gigabytes to manage backups and estimate cloud storage costs. Confusion often arises between binary (1024) and decimal (1000) prefixes used by hardware manufacturers versus operating systems, leading to apparent 'missing' space on hard drives. Accurate conversion helps in planning server capacity, data transfer times, and device purchases.

How to Convert Bytes to Bits

To convert bytes to bits, use the following formula:

b = B × 8

Example: 1 B = 8 b

For example, 5 B = 40 b, 10 B = 80 b, and 100 B = 800 b. For larger values, 1000 B = 8000 b. Conversely, 1 b = 0.125 B. Our calculator above performs this conversion instantly with full precision — no rounding errors.

Common Mistakes to Avoid

Bit vs Byte: 1 Byte = 8 Bits. Internet speed is usually bits (Mb/s), file size is Bytes (MB).
Base 10 vs Base 2: Hard drive makers use Base 10 (1KB=1000B), OS uses Base 2 (1KiB=1024B).
B vs b: MB is Megabyte, Mb is Megabit.

Pro Tips

Storage buying: A 1TB drive usually shows as ~930GB in Windows due to decimal/binary difference.
Data caps: Streaming HD video uses ~3GB/hour.
Backup rule: 3-2-1 rule: 3 copies, 2 media types, 1 offsite.

What is a Byte?

8 bits.

File sizes.

What is a Bit?

The basic unit of information (0 or 1).

Network speeds.

Frequently Asked Questions

How many bits are in 1 byte?

1 B equals 8 b. This is an exact conversion factor defined by NIST.

How do I convert bytes to bits?

Multiply the value in B by the conversion factor. For example, 10 B = 80 b. Use our calculator above for instant results.

Is the bytes to bits conversion exact?

Yes, this conversion is mathematically exact based on the international definition of these units (NIST SP 811).

Can I convert bytes to bits offline?

Yes! OmniConvert runs entirely in your browser — no internet connection needed after the page loads. Your data never leaves your device, ensuring complete privacy.

What is the difference between bytes and bits?

Bytes (B) and Bits (b) are both units of digital storage but belong to different measurement systems. 1 B = 8 b. Use the converter above to switch between them instantly.
