Formula and source

finished_gal = area / coverage_ft2_per_gal; conc_oz_per_gal = oz_per_gal (mode A) or 128/(N+1) (mode B, 1:N by volume); concentrate_oz = finished_gal * conc_oz_per_gal; water_gal = finished_gal - concentrate_oz/128; tanks = ceil(finished_gal / tank); per_tank_conc_oz = conc_oz_per_gal * tank. 128 fl oz per US gallon.
