Useless Fact of the Day

Google Calculator uses the wrong value for a Beard-Second in its calculations.

Quote:

Beard-second The beard-second is a unit of length inspired by the light-year, but used for extremely short distances such as those in integrated circuits. The beard-second is defined as the length an average beard grows in one second. Kemp Bennett Kolb defines the distance as exactly 100 angstroms,[9] (i.e. 10 nanometers), as does Nordling and Österman's Physics Handbook.[10] However, Google Calculator supports the beard-second for unit conversions using the value 5 nm,[11] i.e. half the value according to Kolb and Physics Handbook.
