how many 4 ounce boneless pork chops = One 7 ounce bone-in pork chop?

Hello, I am trying to figure out if I will need to double the recipe I have for "Maple Glazed Pork Chops". Which calls for four (4) bone-in pork chops (7 ounces each) and I have eight (8) thin boneless porkchops. Can someone please help??!!! :-)
