Data Size
Storage calculators and converters for bytes, KB, MB, GB and TB
Four tools for the questions that come up every time storage or bandwidth is involved:
- Storage space calculator — how many photos, videos and songs fit in 64 GB, 128 GB or 1 TB.
- Data size converter — bytes ↔ KB ↔ MB ↔ GB ↔ TB, in decimal (1000) and binary (1024) units.
- Download time calculator — how long a file takes at a given Mbps.
- Bits to bytes — the ×8 that trips up every speed comparison.
