Datenmengen-Umrechner

Convert digital storage and data units: bits, bytes, kilobytes, megabytes, gigabytes, terabytes and petabytes in both decimal (SI) and binary (IEC: KiB, MiB, GiB) units.

Die folgende Anleitung ist noch nicht auf Deutsch verfügbar und wird auf Englisch angezeigt. Der Rechner selbst ist vollständig übersetzt.

So verwenden Sie diesen Rechner

  1. Enter an amount of data.
  2. Choose decimal units (kB, MB, GB = powers of 1,000) or binary units (KiB, MiB, GiB = powers of 1,024).

Formel

Storage manufacturers use decimal prefixes, while operating systems often show binary sizes. That's why a 1 TB drive appears as about 931 GiB.

1 byte = 8 bits
1 GB = 1,000,000,000 bytes
1 GiB = 1,073,741,824 bytes (2³⁰)
1 Mbit = 125,000 bytes

Examples

  1. 1 TB = 10¹² B ÷ 2³⁰ ≈ 931.32 GiB.
  2. A 100 Mbit/s connection transfers 12.5 MB per second.

Häufige Fragen

Why does my 1 TB drive show less space?

The drive has 10¹² bytes, but Windows reports sizes in binary units (labelled 'GB' but meaning GiB), giving about 931.

Is internet speed in bits or bytes?

Bits. Divide Mbit/s by 8 to get megabytes per second.

What do KiB, MiB and GiB mean?

Kibibyte, mebibyte and gibibyte: binary units defined by the IEC to remove ambiguity.
