what is volts amp and watt

Volt-amps = 115 * 8.7 = 1000.5
But you cannot determine VAR or Watts without knowing the power factor of the motor. To determine horsepower, you would need to know the efficiency of the motor in addition to the wattage.
8 to 9 full-load amps is typical for a 1/2 horsepower 120VAC induction motor, but you have to make guesses about typical power factor and efficiency to show that number in a calculation.

115 * 8.7 = 1000 Watts
746 Watts = 1 horsepower, so the horsepower rating is 1.34 horespower
Without knowing the power factor of the motor, I cannot give you the VAR rating.

The above answerer's have mentioned power factor but then gone on to give you an answer??????????
If its ac, you cannot work it out from what you have. Also, horsepower ratings of motors are the output power not the input.
