Usage

Although there is considerable overlap, impracticable and impractical are not used in exactly the same way. Impracticable means ‘impossible to carry out’ and is normally used of a specific procedure or course of action, as in poor visibility made the task difficult, even impracticable. Impractical, on the other hand, tends to be used in more general senses, often to mean simply ‘unrealistic’ or ‘not sensible’, as in in windy weather an umbrella is impractical
