For example, in 2020, the average U.S upload speed was found to be 10.45Mbps, and these speeds generally improve from year to year. But upload speeds this low aren't commonplace in many U.S states. In general, you don't want your upload speed to fall below around 2 or 3Mbps, as this will cause problems while conducting certain activities. So, an upload speed of 10Mbps indicates that you can upload ten megabits (or ten million bits) from your device to the internet every second. So, let's say, for example, that your home Wi-Fi upload speed is 10Mbps (megabits per second).
