No the SI base units are:
- metre for length
- kilogram for mass
- second for time
- ampere for electric current
- kelvin for temperature
- candela for luminous intensity
- mole for the amount of substance.
Voltage is derived from the base units, metre, kilogram, seconds and ampere.
V = m2·kg·s−3·A−1
Definition of voltage
The voltage between two ends of a path is the total energy required to move a small electric charge along that path, divided by the magnitude of the charge.
V = J/C
where:
J=m2·kg·s−2
C=s·A
V = (m2·kg·s−2)/(s·A)
Thus:
V = m2·kg·s−3·A−1

What is magnetic flux measured in?
The SI unit of magnetic flux is the weber (in derived units: volt-seconds)
What is the measure of coulomb?
The coulomb is an SI derived unit used to measure electric charge. It is a special name given to an 'ampere second', which are both SI base units.
What is the difference between ohms and mohms?
ohms is the SI unit of resistance MHO (siemens) is the SI unit of reciprocal of resistance ie conductance
Is the 'ampere' an SI unit?
The ampere is one of the seven SI base units, and is used to measure current. It is defined in terms of the force between two parallel conductors due to the magnetic fields set up around those conductors.
What is the Definition for ohms?
Ohm is the unit for electrical resistance. The definition is given by Ohm's Law: resistance = voltage / current; in SI units: ohms = volts / amperes. For example, a resistance of 1 ohm would result in 1 ampere of current for every volt applied.
What is the base unit of voltage?
The base unit of voltage is the volt, a combined unit meaning joules per coulomb.AnswerThe SI unit for voltage is the volt (symbol: V), which is a derived unit -not a base unit. There are seven base units in the SI system: metre, kilogram, second, ampere, candela, kelvin, and mole. SI units which are not base units are termed 'derived units'.
Is a SI (metric) base unit?
A second is a SI base unit.
How is the electron volt related to the si unit of energy?
The SI unit of energy is the joule. The electron-volt, a non-standard (non-SI) unit, is equal to about 1.6 x 10-19 joule.
What is si unit of e.m.f.?
That's the volt.
What is the SI base unit for temperature?
The SI base unit for temperature is the kelvin.
Which of these are not a SI base unit yard or cm?
Neither is an SI base unit.
What is SI base unit for temperature?
The SI base unit for temperature is the kelvin.
What the si base unit for mass?
The SI base unit for mass is the kilogram
What is the Si base unit for energy?
There is no SI Base Unit for energy. The unit for energy, the joule is a Derived Unit.
Is kilogram an si base unit?
Yes, the kilogram is the SI base unit for mass. Fun fact: the kilogram is the only SI base unit with a prefix.
What is SI base unit of temperature?
Kelvin The SI base unit of temperature is the kelvin.
What is the SI base unit for mass?
The SI base unit for mass is the kilogram
