kg/cm² to MPa (N/mm²)
Updated
1 kg/cm² = 0.0980665 MPa, and 1 MPa = 10.1972 kg/cm². Older Indian practice and site testing quote concrete and soil strength in kg/cm², while IS codes and design use MPa (which is the same as N/mm²). Convert between them, and to psi and bar, below.

210 kg/cm² = 20.594 MPa (N/mm²)
210 kg/cm² in every unit
| kg/cm² | MPa (N/mm²) |
|---|---|
| 100 kg/cm² | 9.807 MPa (N/mm²) |
| 150 kg/cm² | 14.71 MPa (N/mm²) |
| 200 kg/cm² | 19.613 MPa (N/mm²) |
| 210 kg/cm² | 20.594 MPa (N/mm²) |
| 250 kg/cm² | 24.517 MPa (N/mm²) |
| 300 kg/cm² | 29.42 MPa (N/mm²) |
| 350 kg/cm² | 34.323 MPa (N/mm²) |
| 500 kg/cm² | 49.033 MPa (N/mm²) |
MPa and N/mm² are the same thing
One megapascal is one newton per square millimetre — 1 MPa = 1 N/mm² — so an M20 concrete of 20 MPa is 20 N/mm². To convert from the older kg/cm²:
MPa = kg/cm² × 0.0980665 · kg/cm² = MPa × 10.1972

Where you meet each unit
A cube result read as "270 kg/cm²" is 26.5 MPa — comfortably an M25. Steel is graded by yield stress in MPa: Fe500 means 500 MPa. See grade of concrete and IS 1786 TMT bars for how these strengths are specified.
Frequently asked questions
How do I convert kg/cm² to MPa? Multiply the kg/cm² value by 0.0980665. For example, 210 kg/cm² × 0.0980665 = 20.59 MPa.
Is MPa the same as N/mm²? Yes. One megapascal equals one newton per square millimetre, so MPa and N/mm² are identical units and need no conversion.
What is M20 concrete in kg/cm²? M20 concrete has a characteristic strength of 20 MPa, which is about 204 kg/cm². A cube test around 200–210 kg/cm² corresponds to M20.
How many kg/cm² is 1 MPa? One MPa equals 10.1972 kg/cm². So to go from MPa to kg/cm², multiply by about 10.2.
