In order to calculate wattage, you must know the value of the voltage source.
Using Ohms law, you can calculate wattage by multiplying the number of volts by the number of ampers (P=I X E), where P is the power in watts, I is the current in Amperes, and E is the source voltage in Volts.
So, at 240 volts, 100 amperes would represent 240V X 100A = 24,000 watts.
At 120 volts, 100 amperes would represent 120V X 100A = 12,000 watts.
At 12 volts, 100 amperes would represent 12V X 100A = 1200 watts.
Note: This is only completely true for DC (Direct Current) or 100% resistive AC loads. If you're calculating wattage on an inductive load (such as a large tranformer or fluorescent light fixture), for any given amount of current, the actual value for wattage will always be less than that calculated amount.
If you're unsure about the nature of an AC load, you can only use ohm's law as an approximation of wattage. For AC loads, you will often see the term "Volt-Amperes" used instead of "Watts" when calculating the power consumption of AC loads.
To convert amps to watts, you need to know the voltage at which the current is flowing. The formula to calculate watts is watts = amps x volts. Without the voltage information, it is not possible to determine how many watts 900 amps is equal to.
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.
However, In some engineering disciplines the volts are more or less fixed, for example in house wiring, automotive wiring, or telephone wiring. In these limited fields technicians often have charts that relate amps to watts and this has caused some confusion. What these charts should be titled is "conversion of amps to watts at a fixed voltage of 110 volts" or "conversion of watts to amps at 13.8 volts," etc.

85 watts equals zero amps.
In calculating watts, the formula is the same for AC or DC current -- W(Watts) = Volts (V) times Amps (A). Therefore, 12 Volts X 105 Amps = 1,260 Watts.
It depends on the voltage of the system. Once you determine the voltage, the formula to figure out the amperage is: Amps = Watts / Volts

900 watts equal how many amp?
That depends on the voltage available. We assume 120 volts. Then amperage equals power divided by voltage. Amp. = 900 watts / 120 volts = 7.5 amps.
How many watts is in 9 volts?
To calculate the power in watts, you need to know both the voltage and current. Without the current value, you cannot determine the power in watts based solely on voltage.
Mtx thunder 5400x how many watts?
The MTX Thunder 5400x amplifier has a maximum power output of 900 watts.
How many watts has a nutribullet have?
A Nutribullet typically has around 600-900 watts of power, depending on the specific model.
Do you have to use a transformer if your device have 900 Watts 220 V and 60 Hz with 7.5 amps?
If your device uses 900 Watts at 7.5 Amps, then it requires 120 volts. If you want to use it where the supplied current is 220 volts, then you'll need a transformer - but only if the device can operate on 50 Hz. Most places that use 220 Volts supply it at 50 Hz. If your device says it can operate on 50 Hz you can use a transformer.
900 watts equal how many amp?
That depends on the voltage available. We assume 120 volts. Then amperage equals power divided by voltage. Amp. = 900 watts / 120 volts = 7.5 amps.
How many amps does a 110 volt 1.3 kw motor draw?
110 volts divided by 1,300 watts(1.3 kw) = .09 kw or 900 watts.
How many watts is in 9 volts?
To calculate the power in watts, you need to know both the voltage and current. Without the current value, you cannot determine the power in watts based solely on voltage.
How many amps are in 1500 watts?
To calculate the amperage for a given wattage, you would need to know the voltage. However, assuming a standard voltage of 120V in a household circuit, you can use the formula: Amps = Watts / Volts. For 1500 watts at 120 volts, the amperage would be 12.5 amps.
How many watts of cooking power does this microwave have?
According to the manufacturer, the Sharp R-930AK has 900 watts of cooking power.
Mtx thunder 5400x how many watts?
The MTX Thunder 5400x amplifier has a maximum power output of 900 watts.
How many watts has a nutribullet have?
A Nutribullet typically has around 600-900 watts of power, depending on the specific model.
How many pounds does 900 grams equal?
900 grams is equal to 1.98416 pounds.
Do you have to use a transformer if your device have 900 Watts 220 V and 60 Hz with 7.5 amps?
If your device uses 900 Watts at 7.5 Amps, then it requires 120 volts. If you want to use it where the supplied current is 220 volts, then you'll need a transformer - but only if the device can operate on 50 Hz. Most places that use 220 Volts supply it at 50 Hz. If your device says it can operate on 50 Hz you can use a transformer.
900 grams is equal to how many pounds?
900 grams is approximately equal to 1.98 pounds.
Can 2 heaters 900 watts be safe in 1 room with 110 v 15 amps?
no to many currents flowing will cause circuit to heat up and trip breaker if doesn't trip will cause thermal melt down igniting a fire
How many watts does a 1000W microwave use?
1000 W means one thousand watts. That is normally the heating effect that it produces, so the power taken from the supply could be 1500 watts.
