Decimal vs binary units
Storage manufacturers and operating systems may use different calculation systems.
Decimal
1 MB = 1,000,000 B
Uses powers of 1,000 and the symbols KB, MB, GB and TB.
Binary
1 MiB = 1,048,576 B
Uses powers of 1,024 and the symbols KiB, MiB, GiB and TiB.
Byte conversions are calculated entirely inside your browser.
About this tool
What is Byte Converter?
A byte converter translates file and storage sizes between decimal units based on powers of 1000 and binary units based on powers of 1024. This helps explain differences between values such as MB and MiB.

Frequently asked questions
Questions about Byte Converter
What is the difference between MB and MiB?
One megabyte is 1,000,000 bytes, while one mebibyte is 1,048,576 bytes. MB uses decimal powers and MiB uses binary powers.
Why does an operating system show a different file size?
Some systems display binary calculations while labeling them with decimal symbols such as MB or GB, which can make the reported size appear different.
How many bytes are in one gigabyte?
One decimal gigabyte contains 1,000,000,000 bytes. One binary gibibyte contains 1,073,741,824 bytes.
Are values sent to a server?
