I have a friend who rides a 53cm road frame and he wants to know what size MTB frame would he ride.

Trek calls both the 52 cm and 54 cm sizes "small" in their Road 1.5 model. In their 6500 Mountain model, they call 15.5 inches "small". That should give you a starting point, I think. You can't just do a conversion between centimeters and inches. But...take BenLi's advice, and go try the actual bikes.

no no. It's not for me. My friend just wants to get an idea roughly of what size frame he might ride. All I know is that he rides a Merlin. I think it's about a 53cm c-c frame, with a 54.5cm top tube.

Your friend will be looking at a small frame -- probably 15-16". Fit is not as critical on a MTB as it is with a road bike.

Same here. Mtn bike fit can be very important, especially when you start to do more technical trails.

If you are 6' tall then I would garner to say that your 53cm road frame sounds way too small. Unless, of course, your 53cm road frame is a sloping top-tube frame, in which case your frame if measured to a horizontal top tube is actually a lot bigger than 53cm.

Its not slopping, it is too small. Its my commuter. I feel more comfortable on it in traffic then a larger bike. Going to get properly fitting and try out some bikes when it comes time to buy a cyclocross bike though.
