The meter is the standard unit, but since this is roughly equivalent to one yard, we must use much smaller units for microbes. Centimeter (cm) = 0.01 meter (2.54 cm = 1 inch) Millimeter (mm) = 0.001 meter (25.4 mm = 1 inch) Micrometer ( μ m) = 0.001 mm (25,400 μ m = 1 inch) Nanometer (nm) = 0.001 μ m (25,400,000 nm = 1 inch) MICROSCOPY---THE INSTRUMENTS Van Leeuwenhoek’s best microscopes had a single magnifying lens and provided approximately 300X magnification. About 1830, an effective compound (2 lens) microscope was developed. 300X magnification....
