About Pressure Conversions
Pressure units span diverse fields: pascals dominate engineering, atmospheres and bars are used in diving and industrial applications, millimeters of mercury (mmHg) are standard in medicine for blood pressure, and pounds per square inch (PSI) are ubiquitous in tire pressure and pneumatic systems. Weather reports use hectopascals (millibars) or inches of mercury depending on the region. Converting between these units accurately is safety-critical in applications like dive planning, where pressure miscalculations can be life-threatening.

Frequently Asked Questions
How do I convert Torr to PSI?
To convert Torr to PSI, use the conversion where 1 Torr (Torr) = 0.0193367 PSI (psi). For example, 1 Torr = 0.0193367 PSI.
What are common Torr to PSI conversions?
Here are common conversions: 1 Torr = 0.0193367 PSI, 5 Torr = 0.0966836 PSI, 10 Torr = 0.193367 PSI, 25 Torr = 0.483418 PSI, 50 Torr = 0.966836 PSI, 100 Torr = 1.93367 PSI.
When would I need to convert Torr to PSI?
Pressure conversions run through weather forecasting (millibars to inches of mercury), tire maintenance (PSI to bar), diving calculations (atmospheres), industrial engineering (pascals), and medical work (mmHg for blood pressure).
How precise are the conversions?
All conversions use exact factors verified against NIST and ISO standards with up to 10 significant figures of precision. Results are calculated using IEEE 754 double-precision arithmetic, which provides approximately 15-17 significant digits. For temperature and other non-linear conversions, exact formulas are used rather than approximations.
