Context values
Some unit families need one extra value for a physically accurate result.
Megapascal is 1000000 pascal units.
Result = input x 1000 / 1e+6.
Pressure uses the pascal as the base unit.

About Converting Kilopascals to Megapascals
Kilopascal and Megapascal 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: Kilopascal is 1000 pascal units, and megapascal is 1000000 pascal units.
Formula
megapascals = kilopascals × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 kilopascal equals 1000 base units, and 1 megapascal equals 1000000 base units, so dividing one by the other gives the direct kilopascal-to-megapascal factor of 0.001.
Simple example
1 kPa × 0.001 = 0.001 MPa
1 kilopascal = 0.001 megapascals.
Real-world example
35 kPa × 0.001 = 0.035 MPa
35 kilopascals = 0.035 megapascals.

Reverse conversion: Megapascal to Kilopascal
0.001 MPa × 1000 = 1 kPa
0.001 megapascals = 1 kilopascal.

Frequently asked questions
How many megapascals are in 1 kilopascal?
1 kilopascal equals 0.001 megapascals, using the exact defined conversion factor rather than an estimate.
How do I convert kilopascal to megapascal?
Multiply the kilopascal value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert megapascal back to kilopascal?
Use the reverse factor: 1 megapascal equals 1,000 kilopascals. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilopascal?
Kilopascal (kPa) is a unit of pressure.
What is a megapascal?
Megapascal (MPa) is a unit of pressure.
Is the kilopascal to megapascal conversion exact?
Yes. Both kilopascal and megapascal are defined by fixed standards rather than physical artifacts, so the factor of 0.001 used above is exact to as many digits as you choose to display.
