Watts = Volts x Amps. 12 megawatts = 12,000,000 watts. You need to know current to calculate the voltage.
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
Watts are not deadly but it would take 12 micro-watts through the heart to kill someone.
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.
The conversion of watts to amps at a fixed voltage is governed by the equation Amps = Watts/Volts for example 12 watts/12 volts = 1 amp for a US example, a food mixer with a 400 watt motor on a 120 volt supply 400/120 = 3.33amps, fit a 5amp fuse
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)
