Measuring with just multimeter.

Connect your capacitor in series with another capacitor whose value is known. Apply 125 VAC from wall outlet and measure voltage drop on each capacitor. Calculate the value of the unknown capacitor based on inverse proportionate relationship between voltage drop and capacitance.

Example: Capacitor X in series with 10 uF test capacitor. Voltage drop on the 10 uF capacitor is 100 V, and on capacitor X is 25 V. From the formula Ux/Utest = Ctest/Cx, the Cx value is (100x10)/25 = 40 uF.
