I recently submitted a paper that includes formulas related to building physics, such as
Q = K (t_b - t)
Q is the daily heating load,
K is the building's heat loss coefficient, and so on. All the quantities should be familiar to the reader.
A reviewer asks that I provide units for the quantities in this (and other) formulas. But this formula will remain true no matter which system of units I use.
Should formulas include units? If not, how can I tactfully rebut the reviewer's request?
