Are Credits and semester hours the same thing?

I have 30 credits and I need 60 “semester hours” to transfer to a better college. Are they the same thing? If so I will need 30 more credits to complete 60 “semester hours” right?

Yes, semester hours= credits, so you need at minimum another 30 credits to transfer.

At a semester school they are the same thing. At a quarter school, a credit is 2/3 of a semester hour. You’d need 90 quarter credits to have 60 semester hours.
