It... d-depends on the object being measured... the standard m-measurement of length is the metre, but further measurements exist in e-exponents of ten, such as the c-centimetre, which is a factor of zero decimal zero o-one as compared to the m-metre.

For instance, my h-height is expressed as one decimal six four four metres, as I i-informed you earlier, but... it can also be expressed as one hundred sixty four decimal f-four centimetres. The two measurements are... e-equivalent, but it is... g-generally preferable to use metres in the c-case of height, as most humans... f-fall within this range.
