⚙️Data Storage Unit Systems

Decimal (SI) - Base 1000
• 1 KB = 1000 B
• 1 MB = 1000 KB
• 1 GB = 1000 MB
• Used in marketing, file sizes
Binary (IEC) - Base 1024
• 1 KiB = 1024 B
• 1 MiB = 1024 KiB
• 1 GiB = 1024 MiB
• Used in RAM, OS reporting

💡Tips

• GB (decimal) ≠ GiB (binary): 1 GB = 0.931 GiB

• Operating systems typically use binary units (GiB)

• Storage manufacturers use decimal units (GB)

• 1 byte = 8 bits; internet speeds often measured in bits

Frequently Asked Questions

What's the difference between GB and GiB?

GB (gigabyte) uses base 1000 (1 GB = 1,000,000,000 bytes), while GiB (gibibyte) uses base 1024 (1 GiB = 1,073,741,824 bytes). Storage manufacturers use GB, while operating systems often use GiB, which is why a "500 GB" drive shows as ~466 GiB.

How do I convert Mbps to MB/s?

Divide Mbps (megabits per second) by 8 to get MB/s (megabytes per second). For example, 100 Mbps = 100 ÷ 8 = 12.5 MB/s. Remember: 1 byte = 8 bits.

Why does my 1 TB drive show less space?

A "1 TB" drive (1,000 GB marketing) shows as ~931 GiB in your OS because: (1) manufacturers use decimal (base 1000), OS uses binary (base 1024), and (2) some space is used for formatting and system files.

What are KiB, MiB, and GiB units?

These are IEC binary units: KiB (kibibyte), MiB (mebibyte), GiB (gibibyte), TiB (tebibyte). They use base 1024 (powers of 2) and are more accurate for computer memory and storage than decimal units (KB, MB, GB).

How much is 1 GB in bytes?

It depends: 1 GB (decimal) = 1,000,000,000 bytes, while 1 GiB (binary) = 1,073,741,824 bytes. The difference (about 7.4%) becomes significant for large storage capacities.
