Tips & Notes
- ✓Mobile data: video streaming uses ~500-1,000 MB/hour. Calculate monthly plan needs in MB.
- ✓1 GB photo storage = ~500 smartphone photos (2 MB each) or ~125 RAW photos (8 MB each).
- ✓App sizes: mobile apps typically 50-500 MB; games 1,000-5,000 MB (1-5 GB).
- ✓Email storage: Gmail offers 15 GB free = 15,000 MB. Average email with attachment ~1 MB.
Common Mistakes
- ✗Confusing decimal GB (1,000 MB) with binary GiB (1,024 MiB) — 2.4% difference.
- ✗Calculating mobile data in GB then comparing against MB-specified plan limits.
- ✗Ignoring caching — apps cache data that counts against storage, not just the base app size.
- ✗Forgetting OS overhead — Android/iOS uses 5-15 GB for the operating system itself.
Gigabytes to Megabytes Overview
What This Calculator Does
Converts gigabytes to megabytes: 1 GB = 1,000 MB (decimal). Also shows GiB to MiB: 1 GiB = 1,024 MiB (binary).
App and Storage Quota Reference
| GB | MB | Context | |----|-----|---------| | 0.5 | 500 | Mobile data light plan | | 1 | 1,000 | Large mobile game | | 2 | 2,000 | Typical game install | | 15 | 15,000 | Free Gmail storage | | 50 | 50,000 | 4K movie (H.265) |
Mobile Data Usage
Streaming music: ~1 MB/minute = ~60 MB/hour. Streaming video: ~500 MB/hour (SD), ~3,000 MB/hour (4K). A 5 GB plan = 5,000 MB ≈ 10 hours SD video or 1.67 hours 4K.
RAM and VRAM Note
Computer RAM is sold in GiB but marketed as GB. 8 GB RAM = 8,192 MiB (binary) = 8,589.9 MB (decimal). The difference matters when checking if a game fits in GPU VRAM.
