Lift to Drag Ratio Calculator

An online calculator to find the lift to drag ratio of an aircraft. In aerodynamics, it is considered as the amount of lift generated by a vehicle. The ratio is calculated to design aircraft. Use this online Lift to Drag Ratio Calculator to find its ratio with specific lift and drag coefficient. The lift coefficient relates the lift generated by a lifting body to the fluid density and velocity of an area. Drag coefficient quantifies the drag of an object in a fluid.

R = CL / CD Where, R = Lift / Drag Ratio CL = Lift Coefficient CD = Drag Coefficient


An object has the lift coefficient of 6 N and drag coefficient of 8 N.


R = CL / CD
= 6 / 8
= 0.75
