According to six-tenths-factor rule, if the cost of a given unit at one capacity is known, then the cost of similar unit with times the capacity of the first unit is approximately equal to __________ times the cost of the initial unit.

Chemical engineering plant cost index is used for finding the present cost of a particular chemical plant, if the cost of similar plant at some time in the past is known.
The present cost of the plant = $${\text{original cost}} \times \frac{{{\text{index value at present}}}}{{{\text{index value at time original cost was obtained}}}}.$$
The most major component of this cost index is
