Yea, there are some things, given certain sizes, that can directly translate, but most of the time, slight changes have to happen in order to fit the physical nature of thread. And it's not always in favor of simplicity (that's the irony, people think that going simple saves them, it doesn't in every instance).
If you already have something on your
computer that is really close, go with that, otherwise, unless different copy is needed, just convert it and move on.
