When to use this converter
You are comparing file sizes across different tools or platforms — one reports in megabytes, another in gigabytes — and want to confirm they refer to the same amount of data.
You are planning disk storage or a cloud backup and need to convert the total size of your files from gigabytes to terabytes to choose the right plan or drive capacity.
An API, database, or monitoring tool reports data transfer or memory usage in bytes and you want to express it in megabytes or gigabytes for easier reading.
You are estimating download or upload time and need to convert a file size from megabytes to gigabytes, or vice versa, to compare against a quota or speed limit.
Common problems and fixes
The converter uses 1024 but my operating system or drive shows different numbers.
This converter uses binary prefixes: 1 KB = 1024 bytes, 1 MB = 1024 KB, and so on. Some tools and drive manufacturers use decimal prefixes (1 KB = 1000 bytes), which gives slightly larger apparent values. A 500 GB drive may show as 465 GiB in your OS for this reason.
I need to convert bits instead of bytes.
This converter works with bytes. One byte equals 8 bits. To convert bits to bytes, divide by 8 first, then use this tool. Network speeds are commonly expressed in megabits per second (Mbps) — a 100 Mbps connection transfers 12.5 MB per second.
I need petabytes or exabytes but they are not listed.
Petabytes and exabytes are not included. One petabyte equals 1024 terabytes. Convert your value to terabytes first, then apply that multiplier manually for petabyte estimates.
