How to use it
- Enter file size (gb, decimal).
- Enter download speed (mbps).
- Select Calculate (or Generate for random tools).
- Read the answer and any additional results below the form. Check the units and the limits of the method.
Formula and method
Download time = file size × 8000/download speed
Download time = file size × 8000/download speed/60
Download time = file size × 8000/download speed/60
The formula uses the units and definitions shown above. Each input is substituted before the arithmetic is evaluated; the calculated output is rounded for display.
Worked example
File size (GB, decimal): 10, Download speed (Mbps): 100. The result is 800 seconds (download time).
Assumptions and limits
Decimal GB; no overhead, contention or speed variation.
