- Worth noticing
- The calculator states a validated temperature span of -40°F to 180°F and flags results clamped at the dataset boundary.
Field notes
The lookup distinguishes gauge pressure from absolute pressure and displays the conversion basis as 14.696 psi (101.325 kPa) per atmosphere. Its reference table spans several pressure scales, including vacuum in inches of mercury, and the page provides both CSV export and print controls. For automotive checks, the cited 80°F baseline is explicitly tied to a test setup of 1,500–2,000 RPM, MAX A/C, and open doors.
