About Converting Torrs to Decipascals
Torr and Decipascal both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: A torr is 1/760 standard atmosphere, and decipascal is 0.1 pascal units.
Formula
decipascals = torrs × 1333.22368421
This factor comes from each unit's defined relationship to the category's base unit: 1 torr equals 133.322368421 base units, and 1 decipascal equals 0.1 base units, so dividing one by the other gives the direct torr-to-decipascal factor of 1333.22368421.
Simple example
1 Torr × 1333.223684 = 1,333.223684 dPa
1 torr = 1,333.223684 decipascals.
Real-world example
100 Torr × 1333.223684 = 133,322.3684 dPa
100 torrs = 133,322.3684 decipascals.

Reverse conversion: Decipascal to Torr
1 dPa × 0.0007500616827 = 0.0007500617 Torr
1 decipascal = 0.0007500617 torrs.
torrs = decipascals × 0.000750061682704

Frequently asked questions
How many decipascals are in 1 torr?
1 torr equals 1,333.223684 decipascals, using the exact defined conversion factor rather than an estimate.
How do I convert torr to decipascal?
Multiply the torr value by 1333.223684. The converter above does this instantly to whatever precision you set.
How do I convert decipascal back to torr?
Use the reverse factor: 1 decipascal equals 0.0007500617 torrs. You can also use the swap control in the converter above to flip the direction instantly.
What is a torr?
Torr (Torr) is a unit of engineering.
What is a decipascal?
Decipascal (dPa) is a unit of engineering.
Is the torr to decipascal conversion exact?
Yes. Both torr and decipascal are defined by fixed standards rather than physical artifacts, so the factor of 1333.223684 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
