THE VERY EPIC PING CALCULATOR

by PKFreeZZy

50km/31mi = ~1.4ms

Ping (ms) = flying distance ÷ 50 or 31  * 1.4

e.g. The distance between your and your opponent's ISP is 823km/511mi

823km ÷ 50km * 1.4 = 16.46 * 1.4 = 23.044ms

511mi ÷ 31mi * 1.4 = 16.48 * 1.4 = 23.077ms

Assuming you have good internet this is pretty accurate.

Elements that affect ping: seas, ISP-to-ISP connection, Wi-Fi, internet quality

Note: If you're playing someone overseas you are probably connected by ground distance, not flying distance, resulting in higher ping.
