How does digital data conversion work?
Digital data is measured in bits and bytes. One byte equals exactly 8 bits. ConvertAll uses the byte (B) as its reference unit. There are two main systems of multiples: decimal units, based on powers of 1000, and binary units, based on powers of 1024. For example, 1 GB equals exactly 1,000,000,000 bytes, while 1 GiB equals 1,073,741,824 bytes. Understanding this distinction is important when comparing drive capacities, memory and file sizes. This converter measures data quantities, not transfer speeds.
Conversion examples
- 1 byte = exactly 8 bits.

Frequently asked questions
How many bits are in a byte?
One byte contains exactly 8 bits.
What is the difference between MB and MiB?
One megabyte (MB) equals 1,000,000 bytes, while one mebibyte (MiB) equals 1,048,576 bytes. MB uses the decimal system and MiB uses the binary system.
How many MB are in a GB?
One gigabyte (GB) equals exactly 1000 megabytes (MB).
How many MiB are in a GiB?
One gibibyte (GiB) equals exactly 1024 mebibytes (MiB).
How do you convert GB to GiB?
Multiply the number of GB by approximately 0.931322575. For example, 100 GB equals approximately 93.1323 GiB.
What is the difference between GB and Gb?
GB means gigabytes, while Gb means gigabits. One gigabyte equals 8 gigabits. An uppercase B represents bytes, while a lowercase b represents bits.
Why does a 1 TB drive sometimes show approximately 931 GiB?
Manufacturers usually advertise drive capacity using decimal units. A 1 TB drive contains 1,000,000,000,000 bytes, equivalent to approximately 931.323 GiB. Formatting and system data can also reduce usable capacity.
What is the difference between KB and KiB?
One kilobyte (kB) equals exactly 1000 bytes, while one kibibyte (KiB) equals exactly 1024 bytes.
Can I convert Mbps to MB/s using this converter?
This converter handles data quantities rather than transfer speeds. As data rates, 8 Mbps equals 1 MB/s, but Mbps and MB/s are not storage units.
