Boundary Layer Thickness in Free convection Formulas

Boundary Layer Thickness is defined as the distance from the solid body to the point at which the viscous flow velocity is 99% of the freestream velocity. And is denoted by d_x. Boundary Layer Thickness is usually measured using the Meter for Length. Note that the value of Boundary Layer Thickness is always negative.
