Measuring pitch using ppi typically results in a number one higher than measuring in tpi — on the same saw. If your saw is 4 tpi, it will be 5 ppi. Our chart below shows both for clarity — or confusion.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e Don't over-stress about file selection \u003c\/span\u003e .
