A milli voltmeter is suitable for measuring voltage/potential difference in milli volts, thus they measure smaller voltages. A regular voltmeter is used to measure comparatively larger voltages.

The volt.
A voltmeter measures the difference in potential between two points on a circuit. An ammeter measures the amount of current passing through a point in a circuit. Although you often see them packaged together in a tool called a multimeter, they measure different quantities: Voltage, also known as potential difference, measured in volts, and Current, measured in amperes, or just amps. Also, they're used in somewhat different ways: -- The voltmeter simply touches the two points in the circuit between which the voltage is measured. -- The ammeter has the circuit current flowing through it. That means the circuit must be broken briefly, and the ammeter connected into the 'hole', before the current can be measured. (There are instruments that are exceptions, but they're rather specialized. The statement above holds generally true for the common ammeter.)
There are 1000 millimeters (mm) in 1 meter (m), so there are 6000 mm in 6 m. "Milli-" before a unit always means one-thousandth of that unit. So seven millivolts (7 mV) means seven-thousandths of a volt.1 metre = 1000 millimetres so 6 metres = 6000 mm. Simple!
With a voltmeter Keep volt meter terminal on phase and neutral wire and it will show the exact volatage
The rate of change of potential with respect to distance is called potential gradient. its unit is volt per meter or newton/coulomb.
