Answer / Rajani Patwa

M30 concrete refers to a mix with a 28-day compressive strength of 30 MPa (Megapascals) or approximately 4350 psi (Pounds per square inch). The exact conversion factor from MPa to psi is 1 MPa = 145.038 psi. Therefore, the concrete strength at 28 days in psi would be approximately: 30 MPa * 145.038 psi/MPa = 4351.14 psi (rounded to 4351 psi for simplicity).
