F1fan90, centimetres would be between metres and millimetres, as you might expect. To get to this from metres you need to divide by 100 (100 cm in 1m) and would have a power number of -2 instead of the -3 that you would have for a millimetre. It isn't a magnitude that is used very often in Biology, therefore I didnt include it here. I hope this helps.
Centimetres are sometimes used for measuring the size of various pieces of storage equipment (flasks and petri dishes etc.) and i believe are used in the studies of small plants for things like leaf and stem sizes, but I will have to double-check this point. The main time I have witnessed it being used is in UV-Vis spectroscopy and the Beer-Lambert law (A = (E)*c*l) where the path length of light through a sample is measured in centimetres, not millimetres. The cuvettes that are used to hold the sample for these experiments are also measured in centimetres to make this calculation easier.
Very informative Doc. Great for the basics to be taught. Keep up the good work.
Where would centimetres fit into this?

Ok, thanks. When are they used then if it seems to be so rare? I would have thought it would be a common thing to use

Ok cool, thanks!
