Dear Kwan, The question you ask is not as simple as it seems. There is much more to figuring out the right scaling for a piano scale than simply plugging numbers into one formula. Without a reasonably good understanding of piano scales you will still not be able to determine the correct wire sizes for the bass strings of the piano you are working on. Most of this information has been published in the Piano Technicians Journal over the past year. If you want to make a study of this subject I would suggest that you purchase the recently released CD set containing the past 20 years of the Journal. Otherwise you can send the required data to me -- or one of the others on this list that do this work -- and have a new stringing scale calculated for the piano.
