    Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source.

    How to convert watts to horsepower. P (HP) = P (W) / 746. How to convert watts to kVA. The real power P in watts (W) is equal to 1000 times the apparent power S in kilo-volt-amperes (kVA) times the power factor (PF) or cosine of the phase angle φ: P (W) = 1000 ⋅ S (kVA) ⋅ PF = 1000 ⋅ S (kVA) ⋅ cos φ.

    For a dc source the calculation is simply the voltage times the current: W = V x A. However, determining the power in watts for an ac source must include the power factor (PF), so: = V x A x PF for ac systems. The power factor is a unitless ratio ranging from -1 to 1, and represents the amount of real power performing work at a load.
