FlightAware tracking question

FlightAware General

Hi guys, i got a couple of questions about when i’m tracking a flight.

For example when tracking a flight i see the distance as 3,955 SM, What does SM mean? I thought i had seen flights on here with NM next to them, I know what NM stands for but not SM.
