The question doesn't make sense. 18V is a measure of potential difference while horsepower is a measure of power.
If you find out the current, then you can calculate the power and compare the two quantities.
Power (in watts) = Voltage (in volts) * Current (in amps)
and
1 hp = 746 Watts
so
18V * current (in amps) / 746 = power in horsepower. (this assumes the 18V is DC)
36 is to 12 as 18 is to 24.
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts (Doesn't matter if the source is AC, DC, or a combination of both.)
How to convert horsepower to amps? You'd have to make an assumption about volts. If it's running at 220 volts, that would make it 34 Amps. There are 746 watts in a horsepower and Amps = Watts/Volts.
You're trying to convert mechanical force to voltage, and that doesn't work the way you think it does. The voltage doesn't change on account of the truck's horsepower - that's the alternator and voltage regulator which supplies electrical current.
1 horse power=746watt

This bike has about 18 horsepower
It is not possible to answer the question with any specificity because of a lack of info, but perhaps the following will get you on the right track. Electric motors -- on pool filters, vacuum cleaners, drills, saws, whatever -- can be rated in either amps (A) or horsepower (hp) or watts (W). While horsepower and watts are units of power, an amp is not. But if you know the voltage, you can calculate the power in watts, since watts are just amps times volts. If a motor is energized by 18 volts and draws 1.5 A, it's power consumption is 27 W (18 x 1.5). To convert watts to hp, just remember that one hp equals 746 watts. So if your corded saw is rated at, say, 0.25 hp, that's the equivalent of 186 W. Dividing that by 18 volts yields 10.36 A. DAMN, that's a lotta current!
12 volts is less of power than 18 volts drill
You can't compare volts and amps in this context. If you mean 18 Volts vs. 14 Volts then the 18 Volt tool will provide more power for the job.
