How the calculation works
File sizes are measured in bytes and internet speeds in bits per second. There are 8 bits in a byte, so:
Time in seconds = file size in MB × 8 ÷ speed in Mbps
A 32 MB file on a 20 Mbps connection takes 32 × 8 ÷ 20 = 12.8 seconds, or about 14 seconds with overhead. Real downloads are a little slower than the theory, because some of the connection carries network protocol data rather than the file, and because servers and Wi-Fi rarely deliver the full rated speed. The 10% overhead option accounts for that.
Typical download sizes
| File | Typical size |
|---|---|
| Live NetTV for Fire TV | 16 MB |
| Live NetTV for Android TV / Android | 30–32 MB |
| A large streaming app | 50–150 MB |
| Fire OS or Android system update | 300 MB – 2 GB |
| One hour of Full HD video | about 3 GB |
Slower than expected?
If downloads take far longer than the calculator suggests, measure your actual speed with our speed test on the same device. On a Firestick or TV box, a weak Wi-Fi signal is the usual culprit. See how to improve your connection. Need to convert between Mbps and MB/s? Use the speed unit converter.
