Frequently Asked Questions
Common questions about download speeds and calculations
Why is my download slower than advertised?
ISPs advertise speeds in Megabits (Mbps), but files are measured in Megabytes (MB). There are 8 bits in 1 byte, so your theoretical max download speed is roughly 1/8th of your advertised speed.
What is the difference between Mbps and MBps?
Mbps stands for Megabits per second (Internet Speed). MBps or MB/s stands for Megabytes per second (File Transfer Speed). 1 MB/s = 8 Mbps.
How accurate is this calculator?
It provides a mathematical estimate based on constant speed. Real-world speeds fluctuate due to network congestion, server limits, and hardware capabilities.
