Felony is a more serious crime, misdemeanor is a less serious crime.
But there are federal crimes and state crimes, and we have courts for each.
Felony carries a penalty of imprisonment of a year or more. Misdemeanor is less than a year. Some states have a few crimes classified as elevated misdemeanors and can have slightly longer terms available for sentencing, but those are the exception and they diverge from the history where the terms come from.
