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.

∙ 14y agoTo 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.

∙ 14y agoYou 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.

∙ 15y agoIn 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.

∙ 14y agoIt depends on the voltage of the system. Once you determine the voltage, the formula to figure out the amperage is: Amps = Watts / Volts

∙ 12y agoThat depends on circuit voltage.
1 watt is equal to 1 volt times 1 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.
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.
The MTX Thunder 5400x amplifier has a maximum power output of 900 watts.
A Nutribullet typically has around 600-900 watts of power, depending on the specific model.
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.
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.
110 volts divided by 1,300 watts(1.3 kw) = .09 kw or 900 watts.
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.
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.
According to the manufacturer, the Sharp R-930AK has 900 watts of cooking power.
The MTX Thunder 5400x amplifier has a maximum power output of 900 watts.

900 grams is equal to 1.98416 pounds.
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
900 grams is approximately equal to 1.98 pounds.
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.
Rockford Fosgate offers a great selection of 900 watt amps. You can also check reviews on the Kenwood 900 watt mono channel amp.
