Converts between bytes, KB, MB, GB and TB. The 1000-based and 1024-based counts sit side by side so you can see where the notations diverge.
How to use it
- Type the size and the unit
- Compare the two families of values
- Read the difference below
Common questions
- Why does a 1TB drive show as 931GB?
- The manufacturer writes 1TB meaning a trillion bytes, while the operating system counts in steps of 1024 — so the same capacity reads as about 931GiB. No space went missing; the counting differs.
- What is a KiB?
- A notation created to make the 1024 basis explicit. KB means 1000, KiB means 1024.
- Which one is correct?
- Both are in use. Storage and network speeds conventionally use 1000; memory and operating-system displays use 1024.
