The SI unit of voltage is the Volt, which is a derived unit equivalent to a Joule/Coulomb.
A volt is itself a unit.

Ohms measure electrical resistance. The resistance in ohms is the voltage divided by the current.

the voltage drop means whenever the conductor passing through the supply voltage, according to the resistivity property to reduces the some amount of voltage that drop is known as voltage drop for example the resistance is used to drop the voltage to the circuit.............................................

A voltage test meter is used to measure voltage potentials in a circuit.
A voltmeter; or more often today a multimeter. In the past analog meters were used (a needle moved across a scale and you read the value under the needle). Now, meters that can measure several parameters (multimeters) are typically used. To measure voltage you have to select two points that you want to test the voltage between. If you have a resistor (more properly a device that creates resistance and typically uses power to do work) there is a voltage drop related to the power dissipated (Volts = Amperes x Ohms [of resistance]).
The unit used for measure temperature is the kelvin
