Torque conversion formula

Moment of Force Formulas

Basic Formula

τ = F × r

Where: τ = torque, F = force, r = distance

Example: F = 10 N, r = 0.5 m
τ = 10 × 0.5 = 5 N⋅m

Angular Formula

τ = I × α

Where: I = moment of inertia, α = angular acceleration

Example: I = 2 kg⋅m², α = 3 rad/s²
τ = 2 × 3 = 6 N⋅m

Power Formula

P = τ × ω

Where: P = power, ω = angular velocity

Example: τ = 5 N⋅m, ω = 10 rad/s
P = 5 × 10 = 50 W

Cross Product

τ = r × F

Vector cross product for 3D calculations

|τ| = |r| × |F| × sin(θ)
Where θ is angle between vectors
