About Converting Megapascals to Decapascals
Megapascal and Decapascal both show up on pressure gauges — psi is standard on US tire and tool specifications, while bar is the everyday pressure unit across most of the rest of the world. Specifically: Megapascal is 1000000 pascal units, and decapascal is 10 pascal units.
Formula
decapascals = megapascals × 100000
This factor comes from each unit's defined relationship to the category's base unit: 1 megapascal equals 1000000 base units, and 1 decapascal equals 10 base units, so dividing one by the other gives the direct megapascal-to-decapascal factor of 100000.
Simple example
1 MPa × 100000 = 100,000 daPa
1 megapascal = 100,000 decapascals.
Real-world example
35 MPa × 100000 = 3,500,000 daPa
35 megapascals = 3,500,000 decapascals.

Frequently asked questions
How many decapascals are in 1 megapascal?
1 megapascal equals 100,000 decapascals, using the exact defined conversion factor rather than an estimate.
How do I convert megapascal to decapascal?
Multiply the megapascal value by 100000. The converter above does this instantly to whatever precision you set.
How do I convert decapascal back to megapascal?
Use the reverse factor: 1 decapascal equals 0.00001 megapascals. You can also use the swap control in the converter above to flip the direction instantly.
What is a megapascal?
Megapascal (MPa) is a unit of pressure.
What is a decapascal?
Decapascal (daPa) is a unit of pressure.
Is the megapascal to decapascal conversion exact?
Yes. Both megapascal and decapascal are defined by fixed standards rather than physical artifacts, so the factor of 100000 used above is exact to as many digits as you choose to display.
