How it works

Converts digital size between kilobytes, megabytes, gigabytes and terabytes, using 1,024 of each per step.

Worked example

1,024 MB. = 1 GB.

Common mistakes

Confusing bits (b) with bytes (B) — 8 bits make 1 byte.
Mixing decimal (1000) and binary (1024) prefixes.

Frequently asked questions

KB vs KiB?

KB is 1,000 bytes (decimal); KiB is 1,024 bytes (binary). Drives use decimal, RAM uses binary.

Bits or bytes?

8 bits make 1 byte — file sizes are usually in bytes, internet speeds in bits.

Does it use 1024 or 1000 per step?

1,024 (binary), so 1,024 MB = 1 GB. Drive makers often advertise using 1,000, which is why a '1 TB' disk shows less in your operating system.

How accurate are the conversions?

They use standard conversion factors at full device precision, so they're reliable for everyday and professional use.

Does it work offline and stay private?

Yes — the conversion runs entirely in your browser, with no sign-up and nothing sent to a server.
