How can you convert a galvanometer to ammeter and voltmeter?

To convert a galvanometer into an ammeter, you connect a suitable shunt resistance parallel to the coil of the galvanometer.The value of this shunt resistance is low. To convert a galvanometer into a voltmeter you connect a suitable high resistance in series with the coil of the galvanometer.
