An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
A voltmeter measures electrical pressure, which is measured in volts, which is a simplification of joules per coulomb.
Electrical current is measures in amperes.
I suppose you mean weight when you say physical quantity, a galvanometer *doesn't measure weight or mass of an object it measures electrical currents.
Why momentum is the derived quantity
current

a physical quantity is an amout or any property that can be measured.
Physical quantities are quantities that can be measured. For example: water, distance, etc.
The physical property is measured by physical quantities. Examples: a mass is measured in kg, the thermal conductivity is measured by W/m.K, the density is measured by g/cm3.
a physical quantity can be measured, like mass; a nonphysical quantity cannot be measured, like feelings or happiness
pressure
Air pressure is measured in bar.
it is time
Yes, because it can be measured.

Any physical property that can be measured and represented in numbers.
Air pressure is measured in bar.
It is measured using a Voltmeter
Voltage is measured with a voltmeter.
