Grade of concrete is denoted by a number and a letter, such as M25 or C30.
The number represents the strength of the concrete in megapascals (MPa).
The letter represents the type of cement used, such as OPC (Ordinary Portland Cement) or PPC (Portland Pozzolana Cement).
Unit conversion involves converting between different units of measurement, such as converting cubic meters to cubic feet or kilograms to pounds.
Common units used in construction include meters, feet, kilograms, pounds, cubic meters, and cubic feet.
