Torr to Pa Converter

This online converter provides instant and accurate conversion between Torr (a unit of pressure often used in vacuum science) and Pascal (Pa), the SI derived unit for pressure. The core function relies on the established physical relationship: 1 standard atmosphere is approximately 760 Torr, which equals 101325 Pa.

When you input a value in Torr, the tool uses the precise conversion factor (approximately 1 Torr = 133.322 Pa) to calculate the equivalent pressure reading in Pascals. The bidirectional support means you can also convert from Pa back into Torr, ensuring comprehensive unit compatibility for your scientific calculations.

We include reference tables and multiple application examples—from chemistry lab work to industrial vacuum systems—to help you understand the context of these conversions. Simply input your measurement, and receive a reliable conversion instantly.

To ensure the highest quality conversions, always verify the context of your pressure measurement. Before entering a value, confirm what standard (e.g., STP or NTP) the source data was calculated against.

If you are converting between scientific literature and industrial standards, take note that while 1 atm is often cited as 760 Torr, some specialized fields may use slightly different approximations. This tool provides the most commonly accepted conversion factors for consistency.

When performing complex calculations involving multiple units (e.g., converting a pressure gradient from Pa/m to Torr/cm), it is best practice to convert all components into the base SI unit (Pascals) first, and then use this tool for the final conversion step.

Keep your original source data handy—knowing if the pressure was measured at 293 K or 273 K is vital context that affects the final Pa reading.
