MB to GB Converter (Megabytes to Gigabytes)

Q: What is 500 MB in GB?

500 MB is 0,5 GB (500 × 0,001).

Q: What is 1.024 MB in GB?

1.024 MB is 1,024 GB (1.024 × 0,001).

Q: Is 1 GB 1,000 MB or 1,024 MB?

Both are in use. In SI (decimal) units 1 GB = 1,000 MB, used by storage makers, carriers and macOS. In binary (IEC) units 1 GiB = 1,024 MiB, used by Windows and RAM. Windows still writes "GB" for GiB.

Convert megabytes to gigabytes for data plans, file sizes and storage. 1 GB = 1,000 MB, so divide by 1,000. Windows and some apps use binary units, where 1 GiB = 1,024 MiB; the converter shows both.

Rechenweg Schritt für Schritt

Formel: Wert (GB) = Wert (MB) × (1.000.000 ÷ 1.000.000.000)

Schritt 1: 2.500 MB in die Basiseinheit (B) umrechnen: 2.500 × 1.000.000 = 2,5000E9 B.
Schritt 2: Basiseinheit (Byte) in Gigabyte umrechnen: 2,5000E9 ÷ 1.000.000.000 = 2,5 GB.
Direkter Faktor: 1 MB = 0,001 GB.

MB to GB formula

Kurz gesagt: 1 MB = 0,001 GB, so multiply by 0,001: GB = MB × 0,001. Going back: MB = GB × 1.000.

How to convert Megabyte to Gigabyte

SI prefixes are decimal: mega = 10⁶, giga = 10⁹, so 1 GB is 1,000 MB. Drive makers, mobile carriers and macOS use these. Windows reports sizes in binary units (1 GiB = 1,024 MiB = 1,073,741,824 bytes) but labels them "GB", which is why a 500 GB drive shows as about 465 GB.

1. MB → GB

Multiply the number of Megabyte by the conversion factor:

GB = MB × 0,001

Example: 2.500 MB × 0,001 = 2,5 GB.

2. GB → MB

To go back, divide by the same factor, or multiply by its reciprocal, 1.000:

MB = GB ÷ 0,001

Example: 2,5 GB ÷ 0,001 = 2.500 MB.

Shortcut: move the decimal point

To go from MB to GB, move the decimal point three places left. For the binary units Windows shows, divide by 1,024 instead (about 2.4% fewer):

GB = MB ÷ 1,000

2,500 MB = 2.5 GB; in binary, 2,500 MiB = 2.44 GiB.
