Download Time Calculator

Calculate exactly how long large file downloads take across various broadband tiers (Megabits per second vs Megabytes per second).

Understanding the 8:1 Bit-to-Byte Ratio

A common source of confusion among internet subscribers is the difference between Mbps (Megabits per second, used by ISPs to advertise speeds) and MB/s (Megabytes per second, used by Steam, Epic Games, and web browsers to show file download progress). There are exactly 8 bits in one byte. Therefore, a 100 Mbps broadband connection transfers a maximum theoretical speed of 12.5 Megabytes per second.
