CdA Calculator
Choose temperature, altitude, tires, drivetrain efficiency and calculate the CdA for a given power output and speed.
Temperature = °C
Course Altitude = m
Rolling resistance coefficientcoeff. CRR = 0.00
Drivetrain efficiency = %
Weight of rider + bike = kg
Speed = km/h
Power = Watt

About the CdA calculator
Maybe the name CdA Calculator is a little bit misleading. Since one has to make quite a few assumptions under which this Calculator works maybe the name "CdA Estimator" would be more suitable - but who would Google this Keywords ;-).
To name the most important assumptions: flat course and no head or tailwind. Moreover it is difficult to get accurate numbers for the rolling resistance coefficient and the drivetrain efficiency.
Here you can find a Power to Speed Calculator together with some notes on the calculators and the formulas behind them.
