Block Coefficient (Cb)

Calculate Cb from displacement and main dimensions — for use in the Squat / UKC calculator.

Displacement (tonnes)

Water Density (t/m³)

Length LBP (m)

Breadth (m)

Mean Draft (m)

Block Coefficient

Volume of Displacement--

Block Volume (L × B × d)--

Cb = Volume of Displacement ÷ (L × B × draft), where Volume = Displacement ÷ water density. Use this Cb in the Squat / UKC calculator.
