Default CFL number question from novice

Hello,

Can someone find CFL number from Minimum Face Area rather than min length Dl? I know than CFL = (U Dt)/Dl with U being speed, Dt time-step and Dl min length, is there a formula linking CFL to minimum Area?

Thank you for any help and guidance. Happy New Year to All of you!

James
