Frequently Asked Questions
What is the difference between MB and MiB?
A megabyte (MB) is 1,000,000 bytes using the decimal system, while a mebibyte (MiB) is 1,048,576 bytes using the binary system. That is why a MiB is about 4.9 percent larger than a MB.
How many megabytes are in a gigabyte?
Using decimal units there are 1000 megabytes in one gigabyte. Using binary units there are 1024 mebibytes in one gibibyte. The tool includes both.
Why do hard drives look smaller than advertised?
Drive makers count in decimal gigabytes (1000 MB), while many operating systems display binary gibibytes (1024 MiB). The same drive therefore shows a smaller number, even though no space is missing.
How many bits are in a byte?
There are 8 bits in one byte. To convert bytes to bits multiply by 8; to convert bits to bytes divide by 8.
Is my data sent anywhere?
No. The conversion runs entirely in your browser, so the numbers you enter never leave your computer and the tool works offline once loaded.
Can I see decimal and binary units together?
Yes. The table lists decimal units like MB and GB alongside binary units like MiB and GiB, so you can compare both at a glance.
