I facetimed the class while running a kilometer on the treadmill.

The Bacteria Kilometre (or bkm) Formula:

1km = 100000cm Average human height= 170cm Average bacteria length = 5 micrometers or 0.0005cm 100000cm / 170cm = 588.2 588.2 humans make 1km therefroe 588.2 bacteria make 1 bacteria kilometer. 588.2 x 0.0005cm = 0.3cm therefore one bkm is equal to 0.3cm Measurement is constructed
