There are is no watts in an amp. A watt is the product of amps x volts.
A 22VA transformer has a power rating of 22 watts. VA (volt-ampere) is a unit used to measure the apparent power in an electrical circuit.
One mA (milliampere) is simply one one-thousandth of one ampere (amp). So, 72 mA is 0.072 amps, or seventy-two thousandths of one amp.
Watts = Amps x Voltage x Power Factor Hence to compute watts you need to know voltage and power factor. If you have a pure resistive load like a light bulb power factor = 1 and can thus be ignored. If you are asking about residential power, the voltage is 120 VAC so the computation is now trivial.
An ampere is a unit of charge flow rate, while a watt is a unit of energy flow rate. The two units are not directly convertible. More specifically, one ampere is one coulomb per second, while one watt is one joule per second. If you knew how many volts were involved, you could compare, because volts is joules per coulomb.
You cannot convert watts to amps, since watts are power and amps are coulombs per second (like converting gallons to miles). HOWEVER, if you have at least least two of the following three: amps, volts and watts then the missing one can be calculated. Since watts are amps multiplied by volts, there is a simple relationship between them.
770 watts.
Watts = Amps X Volts Grab your calculator!
Since the equation for watts is: Volts * Amps = Watts that would mean 12 Volts * 1 Amp = 12 Watts
Do you mean 'megavolt ampere' (MV.A) or 'millivolt ampere' (mV.A)? By using the incorrect symbol ('mva'), this is not clear.To determine the apparent power, in volt amperes, you divide the true power, in watts, by the power factor of the load. One volt ampere is one-millionth of a megavolt ampere ('MV.A' -not 'mva') -assuming you don't mean 'millivolt ampere' ('mV.A')!
Watts is a unit of power, whereas Amperes is a unit of current. They're related though, along with Voltage, Resistance etc. But they're not the same thing, so to answer your question: There are no watts in an ampere! Power (W) = Voltage (V) x Current (I)
Watts (or kilowatts) and amperes are used to measure different things. Watts is a unit of power; ampere is a unit of current. The relationship (for direct current) is: watt = ampere x volt For AC, the relationship is a bit more complicated: watt = ampere x volt x power factor However, the power factor is often close to one.
The same number as 250 oranges is apples. A watt is a volt times an ampere.
One ampere = one coulomb every second .
One ampere is equal to 1000000 microamperes.

There are no 'volt amperes' in a horsepower. A volt ampere is used to measure 'apparent power', which is an electrical quantity. In other words, you are trying to compare apples with Oranges. You can convert watts to horsepower, because they both measure the same thing: power.
