Note: This is only true for resistive loads like heaters and lightbulbs.
AnswerYou cannot really ask 'How many watts equal how many volt amperes?', because you are describing two different quantities, as explained below:
Alternating-current loads are often combinations of resistance and reactance (reactance is the opposition to current due to either inductance, or capacitance, or a combination of both).
Loads having both resistance and reactance exhibit true power and reactive power.
True power describes the rate at which energy is permanently lost due to the resulting temperature difference between the conductor(s) and the surroundings. True power is associated with purely resistive loads, and is expressed in watts.
Reactive power describes the rate at which energy is alternately stored in a magnetic or electric field then returned to the supply. Reactive power is associated with purely reactive loads, and is expressed in reactive volt amperes.
Apparent power is the vector sum of true power and reactive power, and is expressed in volt amperes.
The relationship between true power and apparent power is:
true power = apparent power x power factor
Power factor varies from zero (purely reactive circuit) to unity (purely resistive circuit). So, true power (in watts) will only equal apparent power (in volt amperes) when the power factor is unity -i.e. in a purely resistive circuit. For all other types of circuit, the true power will always be less than the apparent power.
Yes, you can subtract a megawatt from a gigawatt because they are both units of power but differ by a factor of 1000. One gigawatt is equivalent to 1000 megawatts, so subtracting one megawatt from a gigawatt leaves you with 999 megawatts.
In a purely resistive circuit, the power in kilowatts (kW) is equal to the apparent power in kilovolt-amperes (kVA). Therefore, 1 kVA is equal to 1 kW. However, in circuits with reactive components (inductive or capacitive), the power factor would need to be considered.
By "kav", I'm assuming you mean "thousand-ampere-volts" ... usually represented as "KVA". Watts = (Volts) x (Amperes) x (power factor on the line) KW = KVA x (power factor on the line). The power factor on the line is the cosine of the phase difference between the voltage and current waveforms on the line.
MW stands for megawatts. "mw" (in lower case) stands for milliwatts, however.CommentThe SI convention is that is a unit of measurement is named after someone, then its symbol is always capitalised. So, the symbol for watt is an upper-case 'W'. So, the correct symbol for milliwatt is mW and the correct symbol for megawatt is MW.
340 Kelvins are equal to 152.6 degrees Fahrenheit.
1000 VA = 1 kva
1000 VA = 1 kva
60 gigawatts is equal to 60,000 megawatts since each gigawatt is equivalent to 1,000 megawatts.
9 megawatts a year
There are 250,000 watts in 0.25 megawatts. Mega denotes 1,000,000, so 0.25 megawatts is equal to 250,000 watts.
Yes, 2.8 kVA is equal to 2800 watts. This is because 1 kVA is equivalent to 1000 watts, so 2.8 kVA would be 2800 watts.
12000 BTU is equivalent to approximately 3.51 kVA.
2.5 kVA is equal to 2500 watts.
There are 1,000 watts (W) in a kilowatt (kW) and 1,000 volt-amps (VA) in a kilovolt-ampere (kVA). Therefore, 1 kVA is equal to 1 kW.
To calculate tph to megawatts you need to know how many tph are in one megawatts. The equation is 1 mw is equal to 4 tph.
To convert kilovolt-amperes (kVA) to amps (A), you can use the formula: Amps = (kVA × 1000) / Voltage. For example, at a standard voltage of 400 volts, 900 kVA would equal approximately 1,250 amps (900 × 1000 / 400 = 2,250). The exact number of amps varies depending on the system's voltage.
0 - 1000. KVA times a power factor gives you kilowatts, 1000 x watts. If the power factor is 0, then o watts make up your one kVA; if the power factor is 1, then 1000 watts make up your one kVA. Typical power factor is in the range of .8 to 1.
