All data storage converters
| Converter | Units | Typical use |
|---|---|---|
| Megabytes to Gigabytes | MB → GB | File sizes against storage and quotas |
| Gigabytes to Megabytes | GB → MB | Upload limits and data plans |
| Kilobytes to Megabytes | kB → MB | Image and asset weights |
| Gigabytes to Terabytes | GB → TB | Drives, backups and cloud storage |
| GB to GiB | GB → GiB | Why a drive shows less space than sold |
Common situations
Why people usually need a data storage conversion, and which tool answers it.
A new 1 TB drive shows up as 931 GB on your computer.
It looks like space is missing. The risk: the drive is faulty, or you were sold less than advertised.
An upload form rejects files over 25 MB, and your file size is shown in KB or GB.
Sizes are shown in a different unit from the limit. The risk: the upload fails at the last step, again.
What you need
The file size in the same unit as the limit.
