Data storage units measure the capacity of digital storage devices and file sizes. This converter uses the standard SI (base-10) definitions where 1 KB = 1,000 bytes. These are the units used by storage manufacturers, internet providers, and most modern operating systems. Understanding these conversions is essential when comparing storage devices, estimating download times, or managing disk space.
A megabyte (MB) is 1,000,000 bytes (base 10), while a mebibyte (MiB) is 1,048,576 bytes (base 2). This converter uses the standard base-10 (SI) definitions commonly used by storage manufacturers and internet speed providers.
There are 1,000 gigabytes in a terabyte (using the standard SI definition). When buying a 1 TB hard drive, you get approximately 1,000 GB of storage space.
There are 1,000 megabytes in a gigabyte. A typical smartphone photo is 3-5 MB, so a 64 GB phone can store roughly 13,000 to 21,000 photos.
