Mbps to GB Data Usage FAQ
Everything you need to know about converting internet speed into hourly and monthly data consumption.
Multiply your Mbps speed by 0.45 to get GB used per hour, assuming the connection runs at full speed the entire time. For example, a 100 Mbps connection running continuously for one hour would use approximately 45 GB.
Internet speeds are measured in megabits per second (Mbps), but data usage and storage are measured in megabytes or gigabytes. Since 1 byte equals 8 bits, the megabit value must be divided by 8 to convert it into megabytes before calculating gigabyte usage.
Standard definition video streaming typically uses around 0.7 GB per hour, HD streaming uses roughly 3 GB per hour, and 4K streaming can use 7 GB or more per hour, depending on the platform and bitrate.
No. The Mbps to GB per hour conversion assumes your connection is running at its maximum rated speed for the entire hour. In practice, actual usage depends on what you are doing online, since idle time, buffering, and lower bitrate content use significantly less data than the theoretical maximum.
