How to convert Kilopascals to Megapascals
1 kPa equals 0.001 MPa. Use the converter above for any value, or read the table for common conversions.
MPa = kPa × 0.001 · kPa = MPa × 1000Multiply a kilopascals figure by 0.001 to get megapascals, or divide it by 1,000 to go the other way.
Worked examples
- 1 kPa= 0.001 MPa
- 2 kPa= 0.002 MPa
- 5 kPa= 0.005 MPa
- 10 kPa= 0.01 MPa
- 50 kPa= 0.05 MPa
What these units are
Kilopascals (kPa). A kilopascal is 1,000 pascals. It is the unit for tyre pressure in metric countries, and is used for gas and weather pressures.
Megapascals (MPa). A megapascal is 1,000 kilopascals, or one million pascals. It is used for concrete strength, where structural concrete is typically specified between 20 and 40 MPa.
Bar, atmosphere and psi are exact definitions. Gauges and weather stations round heavily, so treat the last digit as indicative rather than precise.
Checking a kilopascals to megapascals conversion
Pressure units are all defined against the pascal, so the conversion is a multiplication by a fixed number. What makes this dimension awkward is that the numbers sit within tens of per cent of each other, so a small slip looks plausible.
Three of the units are close together on purpose: one bar is 100,000 pascals, one atmosphere is 101,325, and weather reports use millibars and hectopascals, which are the same size. A reading that looks like a unit error is often a genuine difference between gauge pressure and absolute pressure instead.
Checking a pressure conversion means converting through pascals and comparing with a known reference, such as the fact that a bar and an atmosphere differ by about 1.3%. The error to watch for is quoting a pressure without saying whether it is measured above atmospheric pressure or from a vacuum.
