The Dilution Calculator uses the classic equation C1V1=C2V2C_1V_1 = C_2V_2C1​V1​=C2​V2​ to help prepare solutions of desired concentrations. Enter any three values (initial concentration C1C_1C1​, initial volume V1V_1V1​, final concentration C2C_2C2​, final volume V2V_2V2​) and leave the unknown blank — the calculator will solve for it. It supports common concentration units (M, g/L, % w/v) and both mL and L volume units (the form handles conversions automatically). Ideal for lab work, classroom exercises, and quick preparation checks — always verify calculations and lab safety procedures before preparing solutions.
