Man-day A unit of economic value to measure costs incurred on labour. Its value
in terms of currency units may vary from place to place since labour is cheaper at
some places than others. However, it is convenient to work out model cost norms
and basic schedules of rates in terms of man-days so that these may be converted
to costs in terms of local currency when required. Economic analysis is facilitated
across national and regional boundaries when expressed in terms of this unit.

Man-day equivalent A unit of economic value expressed independently of a par-
ticular currency. Costs of materials and services not directly related to labour are
expressed in terms of man-day equivalents (abbreviated to mdeq in this topic). This
is equal to the worth of an average unskilled worker's wages for a day, such wages
being averaged over a large number of actual workers in different regions and sectors
of an economy.

Manure Bulky organic matter consisting of refuse of stables, barnyards, and animal
excreta with or without litter, used for enriching soil fertility and improving its
structure.
