Rachel: 10 mm is <1/2"
Mike: 10mm is 1/2.5"
Rachel: 10 millimeters = 0.393700787 inches according to Dr Google.

4.
A "Doctor" who largely reduced the prestige of licensed medical professionals in the intelligent public's mind between 1998 and 2009.

"Dr Google" belongs to the same Country Club as "Google Esq" "Google CPA," "Google CFA," "Google Broker," "Prof Google," and "Coach Google."
You're 38 years old and you have an IQ over 140. You don't have a medical license or attempt to provide medical treatment to others. You do, however, consult "Dr Google" for your own medical needs on a regular basis and have had a long, successful "Doctor"-patient relationship with 'him.' In recent years, you feel inclined to send "Dr Google" the "thank you" gifts that you used to send to real physicians.
