Ideal data transfer time
Estimate transfer duration from decimal gigabytes and a sustained megabit-per-second rate.
Method and scope
Ideal seconds = decimal file size in GB × 8,000 megabits per GB ÷ transfer rate in Mbps.
Convert file size and a user-provided transfer rate into an ideal lower-bound duration. Intended for Learners, General planning.
Inputs- File size — 1
- Sustained transfer rate — 1
SOURCE AND LIMITS
- IETF RFC 1392, Internet Users’ Glossary, “An octet is 8 bits.” ↗
- NIST, SI prefixes use decimal powers; giga denotes 10⁹. ↗
Assumptions: GB is decimal: 1 GB = 1,000,000,000 bytes. The entered rate is a sustained payload rate in megabits per second. One byte/octet is eight bits.
Limitations: The output is a lower-bound arithmetic estimate based on the supplied rate.
