How do you calculate file download time from file size and bandwidth?

Download Time (seconds) = Total File Size in Bits / Bandwidth in Bits per Second. Since 1 Byte = 8 bits, a 50 Gigabyte (GB) game download equals 50 × 8 = 400 Gigabits (400,000 Megabits). On a 100 Mbps broadband connection, download time = 400,000 / 100 = 4,000 seconds ≈ 66.7 minutes (1 hour 7 minutes). On a 1 Gbps fiber connection, it takes just 6.7 minutes.

What is the difference between Megabits per second (Mbps) and Megabytes per second (MB/s)?

Internet providers advertise bandwidth in Megabits per second (Mbps, lower-case b), while operating systems display file sizes and download speeds in Megabytes per second (MB/s, capital B). Because there are 8 bits in 1 byte, divide your advertised Mbps by 8 to find your maximum theoretical download speed in MB/s (e.g. 100 Mbps / 8 = 12.5 MB/s).

How to Convert Megabit Per Second to Ethernet Fast

Converting Megabit Per Second (megabit/second) to Ethernet Fast (ethernet (fast)) is a core calculation in Data Transfer Rate, which measures the digital bandwidth throughput and transmission capacity of a telecommunications link per second. Because Ethernet Fast is a broader physical scale than Megabit Per Second, converting from megabit/second to ethernet (fast) condenses the numerical figure. It takes 95.367432 Megabit Per Second to equal a single Ethernet Fast (1 megabit/second = 0.0104858 ethernet (fast)). To convert any quantity, multiply by 0.0104858 (or divide by 95.367432).

2. Target SI Bridge (k_target):1 ethernet (fast) = 1 × 10⁸ bit per second (bps)
