Over five million, and under a billion, probably depending on which virus we're talking about.
Millimeters in 1 foot? 1 foot (12 inches/1 foot)(2.54 centimeters/1 inch) = 30.48 centimeters * 10 = 304.8 mm
1 cm = 10 mm therefore the shelf is 450mm 450mm/9mm = 50 books
1 mm = 1000 um
1 inch is how many mm?
1 mm = .1 cm
There are 200 micrometers in 2 mm. Therefore, 20 yeast cells (200/10) could fit across a 2 mm field.
10 mm = 1 cm ⇒ 1 mm = 1/10 cm =
Direct Conversion Formula 1 mm* 1 in 25.4 mm = 0.03937007874 in
1 mm= 1/1000 km
1 meter = 1,000 mm.
