Download Time Calculator
How long will that download take? Enter your file size and internet connection speed to get an accurate download time estimate. Supports all common file size and speed units with automatic conversion between bits and bytes.
Internet speeds are measured in bits per second (Mbps), while file sizes are in bytes. There are 8 bits in a byte, so:
- 100 Mbps connection = 12.5 MB/s actual download speed
- 1 Gbps connection = 125 MB/s actual download speed
Common download times at 100 Mbps:
- Music album (100 MB): ~8 seconds
- HD movie (4 GB): ~5 minutes
- 4K movie (20 GB): ~27 minutes
- Video game (50 GB): ~67 minutes
Note: Real-world speeds are typically 60-80% of your plan's advertised speed due to network overhead and congestion.
