No. PSI usually means gauge pressure (psig) — the difference between the measured pressure and the surrounding atmosphere, which is why a tire reads 0 psi when flat. Absolute pressure (psia) includes atmospheric pressure (~14.7 psi at sea level). This converter converts between pressure magnitudes; it does not add or remove the atmospheric baseline.
