There is no kva in volts, kva stands for kilo = 1000, volt = working voltage, amps = maximum amperage draw at that voltage. eg. 1000 VA =100v at 10 amps or 200v at 5 amps. If you had a transformer that had a primary voltage of 480 volts and you need a secondary voltage at 240, with a maximum load of 5 amps, the transformer rating should be 1.2kva or 1200VA. On the premise 480V primary, amperage will be 2.5 amps. Secondary 240V, amperage will be 5 amps. 480 x 2.5 = 1.2 KVA, 240 x 5 = 1.2 KVA. Transformer size is 1200 VA or !.2 KVA.

∙ 12y agoYou cannot. watt hours are a measure of energy (Joules); to compare amperes
to energy you must know the voltage and the amount of time the current &
voltage were present.
=========================
"kwh" and "amps" have different physical dimensions, they're used to describe
different types of quantities, and they don't convert to each other.
If you absolutely had to come up with a formula that shows some relationship
between those two units, it would look something like this:
KWH = (volts) x (Amps) x (time in seconds) divided by (3,600,000)
"K" = 1,000
"W" = watt (power)
"H" = hour (time)
"WH" = watt-hour (energy)
"volts x amps" = watts power

∙ 11y agoYou cannot convert volt amperes to amperes. The volt ampere is used to measure apparent power, while the ampere is used to measure current. These are two completely-different quantities.

Three phase, kva x 1000/1.73 x E (volts). Single phase, kva x 1000/E (volts).

How do you convert horsepower into amps?
You don't. The units measure different things.
How do we Calculate Kwh to Kvah?
To convert 'kwh' to 'kvah' you first need to measure the length of time. You will then convert this amount to hours by dividing by 3,600. You will then divide this amount by the length of time.
How can you convert 110 amp hours in a battery to kilowatt hours?
Ohm's law is P=VI for single phase and 1000 watts per KW where P,V,I denote power,voltage,current so KW = amps *110/1000. So 9.1 amps gives ~1 KW If three phase, it is adjusted by the square root of 3.
How many amps are used in 241000 kwh in a 3 phase power system?
The voltage can be either 250000 kilovolts or 240 volts, it can't be both so the question can't be answered. <<>> There are zero amps in 250,000,000 volts. Amps can be found using the following equations. Amps = Volts/Resistance in ohms, Amps = Watts/Volts and Amps = Sq root of Watts/Resistance in ohms.
How do you convert kvar to amps?
At what voltage? When you know the voltage then, to get the amps those kilovolt.amps contain, you simply divide the kilovolt.amps by the voltage. <><><> You can't convert kVA (kilovolt.amps) to amps unless you know either the source voltage (as was explained above here in the first answer) or the load resistance which is drawing the current from the source. If you know them both you can use Ohm's Law to get the amperage: I = V / R In words, Ohm's law is: Current (amps) equals voltage divided by resistance (ohms)
How many amps are in a 32 KWH?
There are zero amps in 32 kWh. Watts are the product of amps times volts. Without stating what the voltage is, this calculation can not be made. I = W/E is the formula to find amperage but there has to be a time constant if kWh is used. Usually the question is asked as to how many amps are in 32 kW.
How do you convert amperes into kwh?
50
How do you convert 400 amp of three phase supply into kwh?
By knowing the voltage you could use calculate the wattage. Power equals volts times amps. Divide by 1000 to get kilowatts.
How do you calculate 3 phase motor kWH where voltage are 440 and amps are 11?
To calculate kWh a time component is needed for the hours.
If a fan uses 10 amps plugged into 120 volts AC what is the kWh used?
10 amps at 120 volts is 1200 watts or 1.2 Kw, so in 1 hour it will use 1.2 Kwh
How do you convert dollars per kWh to dollar per Btu?
Divide the dollars per kWh by 3,412.14163
How do you convert 500VA into amps?
4.3 amps
Convert 18 VDC to AC amps?
Amps is amps be it DC or AC.
Convert dollars mwh to cents kwh?
If you mean dollars PER mwh and cents PER kwh, divide by 10.
How do you calculate 1 phase kwh from measuring amps?
You can't. Measure the amperes simply tells you what the current is.
How do convert watts to amps?
Watts are the product of amps x volts.
What is the kwh of 2 hp motor at 4500 rpm?
1hp = 746 watts, so 2hp would be 1492 watts, or almost 1.5 kw kWh does not convert to hp, as kWh has a time component.
