The number of amps can be calculated using the formula: Amps = Watts / Volts. If we assume a standard voltage of 120V, then 746 watts is equal to approximately 6.2 amps.
A 0.75 horsepower (hp) is equal to approximately 560 watts.
To calculate horsepower, use the formula: Horsepower = (Voltage x Current x Efficiency) / 746 Given 110 volts and 7 amps: Horsepower = (110 x 7) / 746 Horsepower ≈ 1.03 hp
One horsepower is approximately equal to 745.7 watts.
To convert watts to horsepower, divide the wattage by 746. So, 1200 watts is roughly equivalent to 1.61 horsepower.
2 horsepower is equal to approximately 1492 watts.
