How the Download Rate is Calculated
Calculating download time involves converting your file size and connection speed into the same base units. The most critical distinction is between Megabits (Mb) and Megabytes (MB). There are 8 bits in every 1 byte.
Internet service providers (ISPs) usually advertise speeds in Mbps (Megabits per second), while file sizes on your computer are shown in MB or GB (Megabytes or Gigabytes).
Example Calculation:
If you are downloading a 10 GB game on a 100 Mbps connection:
1. Convert 10 GB to Megabytes: 10 * 1,024 = 10,240 MB.
2. Convert Megabytes to Megabits: 10,240 * 8 = 81,920 Megabits.
3. Divide by speed: 81,920 / 100 Mbps = 819.2 seconds.
4. Result: Approx. 13 minutes and 39 seconds.

Factors That Affect Download Speed
- Network Congestion: If many people are using the same network, speeds will drop.
- Wi-Fi vs. Ethernet: A wired connection is almost always faster and more stable than Wi-Fi.
- Server Limits: Even if you have 1 Gbps fiber, the server you are downloading from might cap speeds at 10 Mbps.
- Hardware: Older routers or network cards may not support modern high-speed connections.
Common File Size Benchmarks
To give you a better idea of what to expect, here are typical sizes for common downloads:
| Content Type | Average Size |
|---|---|
| HD Movie (90 min) | 4 GB – 6 GB |
| 4K Ultra HD Movie | 20 GB – 50 GB |
| Modern AAA Video Game | 60 GB – 150 GB |
| High-Quality Music Album | 100 MB – 300 MB |
