Digital Storage Converters

These converters use decimal SI units: 1 KB = 1,000 bytes, 1 MB = 1,000 KB, 1 GB = 1,000 MB. Storage manufacturers and network engineers use this scale, so a "500 GB" drive holds exactly 500,000,000,000 bytes. The binary equivalents — KiB, MiB, GiB — use 1,024 instead, which is why your OS reports that same drive as roughly 465 GiB. And 8 bits make 1 byte, the link between the bit-based world of network speeds and the byte-based world of file sizes.

The gap between decimal and binary matters every time you buy storage or read a speed spec. A 100 Mbps internet connection moves 100,000,000 bits per second — divide by 8 to get bytes, then by 1,000 to reach kilobytes, landing at 12,500 KB/s. Converting between MB to KB or megabytes to gigabytes is straightforward arithmetic, but mixing decimal and binary mid-calculation is where errors creep in. All 11 tools here stay on the decimal SI scale throughout.

Bits show up most in bandwidth and transfer-rate specs; bytes dominate file sizes, RAM, and disk capacity. Jumping between them — say, working out how many gigabytes map to a given number of gigabits — is a daily task for anyone dealing with video encoding, cloud storage pricing, or network provisioning.
