Megabytes

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.

Frequently Asked Questions

1 GB (decimal) = 1,000 MB. 1 GiB (binary) = 1,024 MiB. Most consumer contexts use decimal: 1 GB = 1,000 MB.

15 × 1,000 = 15,000 MB. If you have 15 GB free storage, that is 15,000 MB or 15,000,000 KB.

At 720p (1.5 Mbps): 1 GB lasts about 1.5 hours. At 1080p (5 Mbps): about 27 minutes. At 4K (25 Mbps): about 5 minutes.

At 2 MB per JPEG smartphone photo: 1,000 MB ÷ 2 MB = 500 photos. At 20 MB per RAW DSLR photo: 50 photos.
