The Stanton number, St, is a dimensionless number that measures the ratio of heat transferred to a fluid to the thermal capacity of fluid. It is used to characterize heat transfer in forced convection flows.It can also be represented in terms of the fluid's Nusselt, Reynolds, and Prandtl numbers.

St = Nu/Re Pr.

Where,
Nu is the Nusselt number.
Re is the Reynolds number.
Pr is the Prandtl number.
