Questions
How many megabytes are in a gigabyte?
There are 1,024 megabytes (MB) in one gigabyte (GB) using binary (IEC) units, or exactly 1,000 MB using decimal (SI) units. This tool supports both standards so you can convert accurately for storage or networking contexts.
What is the difference between MB and MiB?
MB (megabyte) in the SI standard equals 1,000,000 bytes, while MiB (mebibyte) in the binary IEC standard equals 1,048,576 bytes. Operating systems often use binary values but display them with SI labels, which is why a 256 GB drive may show less available space.
How do I convert bytes to a human-readable file size?
Enter the byte count and the tool shows the value in KB, MB, GB, and TB. It picks the most readable unit automatically, so 1,048,576 bytes displays as 1 MiB or 1.05 MB.
Does the byte converter work offline?
Yes, all calculations run in your browser with no server calls. Once the page is loaded you can convert values without an internet connection.
