A standard 3,000 psi concrete is equivalent to roughly 20 MPa. Some countries also define concrete types by compressive strength, using a standard nomenclature not found in the U.S. In India, for example, concrete grades are rated using the letter M, followed by a number, where the number represents the compressive strength in MPa.

IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm2.
