You’ve asked several variations of the conversion question from centimeters to inches.
The short answer is take your measurement in centimeters and divide it by 2.54.
Do it for yourself a few times so that you are comfortable with the conversion. After that, you can just ask Google. There is no need to post more questions here in Y!A on this topic.
I typed your exact phrasing into Google and it immediately returned the value as 1.9685 inches
In other words, just a hair under 2 inches (i.e. about 1 31/32 inch)
