If i look at MSFS bandwidth system requirements min is 5, recommended is 20 and ideal is 50mbps. when i make Speedtest i get download at 50. and when i download anything from the internet Chrome shows me download speed of 5 Mbps. Does this means i got the minimum requirement or the ideal ? i dont understand the value i get from the speed test to the actual download speed.

When you do a speedtest the results are in bits per second (so your getting 50 megabits/sec) when you download a file in chrome it shows in bytes per second. There are 8 bits in one byte so you can multiply the chrome download speed by 8 to convert to bits/sec which should be close to the speedtest result
