Calculate Cadans

I have an edge 830 an di2 connection ( d-fly)

So i know my gear wheel combination ( 50/17 p.e.) and i know my speed ( 30 km/h p.e. ) (how) can i calculate my cadans ??

Thnx for a solution.

Cad = formatnumber((Tb * speed_raw * 60) / (Tf * C))

Cad ... cadence

Tb ... number of teeth back

Tf ... number of teeth front

C ... circumfence of the back-wheel (meter)

(I have not tested the formula. Hopefully I did it right...)
