A typical 12V starter motor for a car can range from 500 to 2,000 watts, depending on the size and design of the motor.
To calculate the amps for a jump starter with 500 watts, you can use the formula: Amps = Watts / Volts. If assuming a standard 12-volt car battery, the calculation would be 500 watts / 12 volts = 41.67 amps.
Watts are not deadly but it would take 12 micro-watts through the heart to kill someone.
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
You asked the wrong question. You need to know how many amps the motor uses. Then you can multiply amps times volts and get watts. Then you can multiply watts by hours and get watt hours. (For house electricity you pay for kilowatt hours.) A kilowatt is 1,000 watts.
It depends on the battery's voltage. Such a battery's capacity is given in ampere-hours, not amperes. An 850 amp-hour 12 volt battery can theoretically operate a 12 volt motor for about 12 minutes but in practice it's probably, maybe a lot less, since the motor will probably stop as the battery nears its depletion.
To calculate the amps for a jump starter with 500 watts, you can use the formula: Amps = Watts / Volts. If assuming a standard 12-volt car battery, the calculation would be 500 watts / 12 volts = 41.67 amps.
To determine this you will have to measure the amperage the starter draws when you crank the engine. This amperage times the voltage (12 volts) will give you the wattage. There are 746 watts to 1 HP.
12 volt systems are not measured in watts...... doofus
There are zero milliamps in 12 watts.
72 watts

Depends on how big the motor is. A stronger motor will draw more amps then a weaker or less efficient motor. For example a wiper motor draws far less then a starter motor.
For calculation purposes 1 HP is equal to 746 watts. So you have a total of 746 x 7 = 5222 watts. The amperage will be A = W/V = 7222/12 = 435 amps. You can not start the motor directly off of the solar panel. You would need a large 12 VDC parallel connected battery bank to obtain the amperage capacity to start the motor. The solar panels would be connected to the battery bank and used to charge the batteries after the start.
A 1 hp electric motor draws ABOUT 746 watts. Multiply volts times amps to get watts. a 1/2 hp motor will use about 3.1 amps @ 120 volts. A 12 hp motor is a VERY large motor, and will draw 8900-9000 watts of power (and use 220-440 volt power)

Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
Voltage of the pump (12) multiplied by the current draw = the watts used. This would be 12 watts if the current was 1 amp, 24 watts if the current is 2 amps, and 36 watts if the current is 3 amps, and so on...
