Unit Relationships
Decimal: 1 KB = 1000 B | 1 MB = 1000 KB | 1 GB = 1000 MB
Binary: 1 KiB = 1024 B | 1 MiB = 1024 KiB | 1 GiB = 1024 MiB
Frequently Asked Questions
What's the difference between KB and KiB?
KB (kilobyte) = 1000 bytes (decimal/SI). KiB (kibibyte) = 1024 bytes (binary). Operating systems often use binary but display decimal labels, causing confusion about actual storage capacity.
Why is my hard drive smaller than advertised?
Manufacturers use decimal (1 GB = 1,000,000,000 bytes) while operating systems use binary (1 GiB = 1,073,741,824 bytes). A '500 GB' drive shows as ~465 GiB in your OS.
How many megabytes in a gigabyte?
In decimal: 1 GB = 1000 MB. In binary: 1 GiB = 1024 MiB. For everyday use, think of 1 GB as roughly 1000 MB.
What's the difference between bits and bytes?
1 byte = 8 bits. Bytes (B) measure storage. Bits (b) measure data transfer speed (like 100 Mbps internet). Don't confuse MB (megabytes) with Mb (megabits).
