There was surely a typing error, it should be 1bar=10N/cm^2. This demonstartes how dangerous the Units conversion could be and how quick it happens.

Thats's a textbook example for my statement I made above. Thanks.

Decades ago, I learned 1 hPa = 1 mbar (which I never forgot). I also remember that Pa is an SI unit, so obviously 1 Pa = 1 N/m². Looking to your book telling something about 10 N/m² I know now that are 10 Pa = 0.1 hPa = 0.1 mbar = 0.0001 bar. No witchwork, just bare simplicity - no calculator needed for that. Did I tell you I like SI?
