In brief: Not exact.
Ritalin is the brand name for methylphenidate (mph), and Adderall (dextroamphetamine and racemic amphetamine) is the brand name for amphetamine (amp).
Mph is about half as potent as d-amp, so 20 mg of methylphenidate would be roughly 10 mg of d-amp. But, Adderall (dextroamphetamine and racemic amphetamine) is a mix of d- and l-amp, and only d-amp is active; so, the ritalin/adderall ratio is more like 20/15. As dr. Hoffman said: little, especially adding in individual differences.
