MB to GB Converter (Megabytes to Gigabytes)
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.

Explicação matemática passo a passo
- Passo 1: converta 2.500 MB para a unidade base (B): 2.500 × 1.000.000 = 2,5000E9 B.
- Passo 2: converta bytes (base) para gigabytes: 2,5000E9 ÷ 1.000.000.000 = 2,5 GB.
- Fator direto: 1 MB = 0,001 GB.

Megabyte: 1.000 KB — fotos e músicas
MB to GB formula
Resposta direta: 1 MB = 0,001 GB, so multiply by 0,001: GB = MB × 0,001. Going back: MB = GB × 1.000.
How to convert megabytes to gigabytes
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 megabytes by the conversion factor:
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:
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):
2,500 MB = 2.5 GB; in binary, 2,500 MiB = 2.44 GiB.

Perguntas frequentes
What is 500 MB in GB?
500 MB is 0,5 GB (500 × 0,001).
What is 1.024 MB in GB?
1.024 MB is 1,024 GB (1.024 × 0,001).
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.
How many photos or videos fit in 1 GB?
Roughly 250–400 phone photos at 2.5–4 MB each, or about 7 minutes of 1080p video at 20 Mbps. Exact numbers depend on resolution and compression.
