Megabyte (MB) to Gigabyte (GB) Calculator
Enter a value in megabytes and choose how you want to convert it.
How to use this megabyte to gigabyte calculator
This tool helps you convert MB to GB in seconds. It supports both common standards used in real life:
- Decimal: Used by hard drive brands, internet plans, and most marketing labels (1 GB = 1,000 MB).
- Binary: Used by many operating systems and technical contexts (1 GiB = 1,024 MiB).
Type your megabyte value, pick the standard, and click Calculate. You’ll get the main result plus a side-by-side comparison for clarity.
MB vs GB: what’s the difference?
Megabyte (MB)
A megabyte is a smaller digital storage unit. Files like photos, short videos, and documents are often measured in MB.
Gigabyte (GB)
A gigabyte is larger and is usually used for apps, games, phone storage, SSDs, and data plans. Since 1 GB contains many MB, converting between them helps you estimate space quickly.
MB to GB conversion formulas
Use one of these formulas depending on context:
- Decimal formula: GB = MB ÷ 1,000
- Binary formula: GiB = MiB ÷ 1,024
Example: 2,000 MB ÷ 1,000 = 2 GB (decimal).
Example: 2,048 MB ÷ 1,024 = 2 GiB (binary).
Common MB to GB conversions
| Megabytes (MB) | Decimal GB (÷1000) | Binary GiB (÷1024) |
|---|---|---|
| 100 MB | 0.1 GB | 0.09765625 GiB |
| 500 MB | 0.5 GB | 0.48828125 GiB |
| 1,000 MB | 1 GB | 0.9765625 GiB |
| 1,024 MB | 1.024 GB | 1 GiB |
| 1,500 MB | 1.5 GB | 1.46484375 GiB |
| 2,048 MB | 2.048 GB | 2 GiB |
| 5,000 MB | 5 GB | 4.8828125 GiB |
| 10,000 MB | 10 GB | 9.765625 GiB |
Why this conversion matters
- Cloud storage planning: Estimate how many files fit in your account.
- Phone and laptop cleanup: Understand what file folders are consuming space.
- Download limits: Translate MB-based files into GB-based monthly data caps.
- Backup strategy: Choose the right drive size for photos, videos, and project archives.
Frequently asked questions
Is 1024 MB equal to 1 GB?
In binary notation, 1024 MiB equals 1 GiB. In decimal notation, 1024 MB equals 1.024 GB. Both can be correct depending on the standard being used.
Why does my computer show less space than advertised?
Manufacturers usually advertise storage in decimal GB, while operating systems may display binary GiB values. This difference creates the appearance of “missing” space.
How many GB is 2048 MB?
Using decimal, 2048 MB = 2.048 GB. Using binary, 2048 MiB = 2 GiB.
Final takeaway
The MB-to-GB conversion is simple once you know which standard applies. Use decimal for product labels and data plans, and binary for many technical or system-level readings. This calculator gives you both perspectives so your storage math stays accurate.
