In U.S. customary units, it is measured in foot pounds (ft lbf) (also known as \"pounds feet\"). Mathematically, the torque on a particle (which has the position r in some reference frame) can be defined as the cross product: (τ = r x F) where, r is the particle's position vector relative to the fulcrum  F is the force acting on the particles,  or, more generally, torque can be defined as the rate of change of angular momentum: (τ = dL/dt) where, L is the angular momentum vector  t stands for time."@en .

In the simple case of direct current circuits, electric power can be calculated as the product of the potential difference in the circuit (V) and the amount of current flowing in the circuit (I): (P = VI), where (P) is the power, (V) is the potential difference, and (I) is the current. However, in general electric power is calculated by taking the integral of the vector cross-product of the electrical and magnetic fields over a specified area."@en .
