How to use it
- Type the value in the kilopascals box.
- Read the result in megapascals as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
MPa = kPa × 0.001
Multiply the value in kilopascals by 0.001 to get megapascals.
Example
To convert 25 kPa to megapascals: 25 × 0.001 = 0.025 MPa.

About the units
- Kilopascal
- Exactly 1000 pascals, widely used for tyre pressure and engineering systems.
- Megapascal
- Exactly one million pascals, used for concrete and steel strength and hydraulics. It equals one newton per square millimeter.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many megapascals are in one kilopascal?
1 kPa = 0.001 MPa exactly.
How do I convert kilopascals to megapascals?
Use MPa = kPa × 0.001. For example, 25 kPa = 0.025 MPa.
How many kilopascals are in one megapascal?
1 MPa = 1,000 kPa.
What is the difference between gauge and absolute pressure?
Gauge pressure is measured from the surrounding air pressure, while absolute pressure starts from a perfect vacuum. These converters change the unit only, so a gauge reading stays a gauge reading.
Are torr and mmHg the same?
Almost. One torr is 101325/760 Pa, about 133.322368 Pa, and one conventional mmHg is 133.322387 Pa, a difference of less than one part per million. For everyday use you can treat them as equal.
