MB to GB – Fast Megabytes to Gigabytes Conversion (1 GB = 1024 MB)
Convert MB to GB instantly. Uses the binary (IEC) standard: 1 GB = 1024 MB. Enter any value above or use the general multi‑unit converter for other formats.
1. Formula
GB = MB ÷ 1024 | MB = GB × 1024
Example: 3072 MB ÷ 1024 = 3 GB
2. Quick Reference
- 256 MB = 0.25 GB
- 512 MB = 0.5 GB
- 1024 MB = 1 GB
- 2048 MB = 2 GB
- 4096 MB = 4 GB
- 8192 MB = 8 GB
3. How to Convert
- Take your MB value.
- Divide by 1024 (binary base).
- Round to 2–3 decimals for display.
- Need decimal marketing GB? Use ÷ 1000 instead.
4. Common Uses
Comparing app sizes, RAM usage, backup estimates, email attachment limits, hosting quotas, log growth planning.
5. Accuracy Tips
- OS/file tools use 1024 base; drive vendors advertise 1000 base.
- For binary clarity, IEC prefers GiB (gibibyte) vs GB (gigabyte).
- Large multi‑file sums: accumulate in bytes first, then convert.
6. Worked Examples
512 MB → 512 ÷ 1024 = 0.5 GB
1536 MB → 1536 ÷ 1024 = 1.5 GB
12288 MB → 12288 ÷ 1024 = 12 GB
7. Quick FAQ
Why does my 500 GB drive show less? Manufacturer uses decimal; OS shows binary.
MB vs MiB? MiB = 1,048,576 bytes (binary). This tool treats MB as binary for practical usage.
Safe rounding? Keep 2 decimals for user display, full precision for math.
