How do I calculate horsepower?
The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.
How do you calculate volts to horsepower?
Use this formula to estimate motor horsepower: Horsepower (hp) = Voltage x Amerage x % EFF x power factor x 1.73/746.
How do you calculate current from voltage and horsepower?
In order to calculate the current from the horsepower and voltage, you must also know the efficiency of the circuit. Multiply the amount of horsepower by 746. For example, if you had 4 hp, you would get 2,984. Divide the result from step one by the voltage.
How many HP is 2.1 amps?

How do you calculate watts from volts and amps?
Obtain Watts from Amps and Volts: Insert the number of Amps (A) and Volts (V) below and click on Calculate to obtain Watts (W). The formula is (A)*(V) = (W). For example, if you have a current of 2 A and a voltage of 5 V, the power is 2A * 5V = 10W.
What is a horsepower equal to?
The electrical equivalent of one horsepower is 746 watts in the International System of Units (SI), and the heat equivalent is 2,545 BTU (British Thermal Units) per hour. …
How do you calculate watts from volts and horsepower?
Watts to Electric Horsepower Since electric horsepower is equal to 746 watts, the formula to find electric horsepower is the power in watts divided by 746.
How do you calculate the horsepower of an electric motor?
Using the formula (V * I * Eff)/746=HP, determine your electric motor’s horsepower. Multiply the voltage, the current, and the efficiency, then divide the result by 746. For example, the horsepower of a 230v motor pulling 4 amps and having 82% efficiency would equal 1 horsepower.
What is the formula for converting volts to amps?
To convert volts to amps, a measure of current, it’s possible to use a formula defined by Watt’s Law. Watt’s Law states that current = power ÷ voltage. Power is measured in watts and voltage is measured in volts. Thus, to find amps substitute the volts and watts in the formula: Current(A) = Power(W) ÷ Voltage(V)
What is the formula to calculate amps?
The formula to find amps using the power factor is: amps = (kW × 1,000) ÷ (PF × volts) For example, find the current of a 5kW generator with an efficiency of 80% at 120 volts.
What is formula for amperage to horsepower?
DC Amps to HP: HP = (E*I*%EFF)/746
How to Convert Amps to Horsepower. The conversion from amps, a measure of electric current, to horsepower, a measure of power output by a motor, can be done using a fairly simple formula. Horsepower = (Amps × Volts × Efficiency) ÷ 746.
