Data Storage Converter
Convert between 9 units of digital data storage — bits, bytes, kilobytes, megabytes, gigabytes, terabytes, petabytes, megabits, and gigabits.
About the Data Storage Converter
Digital data is stored and transmitted in bits and bytes. One byte equals 8 bits. The prefix meanings differ between the decimal SI system (1 KB = 1,000 bytes) and the binary system used by operating systems (1 KiB = 1,024 bytes). Our converter uses the binary (powers of 2) definition consistent with how operating systems report file and drive sizes.
- ›A single HD movie file is typically 4–8 GB; a 4K Blu-ray can exceed 100 GB
- ›The entire written works of humanity are estimated at around 50 petabytes
- ›A standard CD holds 700 MB; a Blu-ray disc holds 25 or 50 GB
- ›Modern SSDs can read data at over 7,000 MB/s (7 GB/s)
