Calculate

File size

File size unit (bytes)

Bandwidth

Rate unit (bits/s)

1 byte = 8 bits. MB = 1,000,000 bytes; MiB = 1,048,576 bytes. Network bandwidth uses decimal bit units.

Estimated transfer time

Minimum transfer time: 1m 20s
Duration in seconds: 80
File size in bytes: 1,000,000,000
Formula: file bytes × 8 ÷ bits per second

Ideal sustained transfer, excluding protocol overhead, congestion, retries, and storage limits. Real transfers usually take longer.
