Hg to mmHg?

So right now i'm studying the gas laws which are fairly easy. My only problem is that the book gives me simple examples how how to do certain problems and when they give me problems to try, it always gives me something that isn't shown in an example. I know how to convert atm pressure to torr and etc. But this question is asking me to convert 24.9 in Hg to (some unit of pressure) which is easy for me to do if i knew how to convert Hg to mmHg. Unfortunately the book doesn't give me that, nor any other source that i could find which was either at home or online. The textbook only gives me inches of Hg in atm, which is 29.92 Hg in 1 atm. Can anyone tell me what the conversion factor for Hg to mmHg is? thank you!
